We granted certiorari to resolve a conflict between two decisions of the court of appeals. In
In re Estate of David,
I.
The facts are not in dispute. Alan W. Blixt (Alan) and Gerald R. Blixt (Gerald) (collectively, the sons) are the natural children of Robert W. David (David). The sons were adopted in August 1961 by James J. Blixt, the second husband of their natural mother, in a step-parent adoption.
David died intestate in 1986. He left no spouse. In addition to his sons, he was survived by three brothers, a fourth deceased brother’s children, and three sisters (collectively, the siblings). The siblings filed a petition in Adams County District Court for adjudication of intestacy аnd appointment of David’s sister, Lillian R. Snel-son, as personal representative of the estate. The sons opposed Snelson’s appointment. They sought to have Alan appointed personal representative, arguing that the General Assembly in 1977 amended the 1961 inheritance law to permit adopted children to inherit from their natural parents.
The district court held that Alan had no right to be appointed personal representative of David’s estate because the sоns’ right to inherit from David was divested when they were adopted in August 1961. The court examined the language of the sons’ adoption decrees as well as the adoption laws in effect in August 1961. It concluded that the sons’ adoption decrees incorporated by reference the law in effect at the time of adoption. It also noted that an inheritance statute in effect since May 1961 prohibited adopted children from inheriting from natural parents. As a result, it concluded that the effeсt of the August 1961 adoptions was to divest the sons of the right to inherit from their natural father.
A divided panel of the court of appeals affirmed the judgment of the district court. The majority recognized that the heirs of an estate are determined by interpreting the law of inheritance existing at the date of the intestate’s death.

II.
Whether children may inherit by intestate succession from natural parents whose parental rights and obligations were terminated by final decree of adoption is a question of first impression in Colorado.
The right of adopted children to inherit is determined by the inheritance laws in effect when the intestate died.
Estate ofWarr,
(1) If, for purposes of intestate succession, a relationship of parent and childmust be established to determine succession by, through, or from a person:
(a) An adopted person is the child of an adopting parent and of the adopted person’s natural parents insofar as the rights of all persons to inherit from or through the adopted person and the right of the adopted person to inherit from or through any person are concerned, except to the extent that inheritance rights have been divested by a final order of relinquishment, a final decree of adoption, or an order terminating the parent-child relationship under the laws of this state or of any other jurisdiction.
6B C.R.S. (1987) (emphasis added). Section 15-ll-109(l)(a) therefore creates a general rule and an exception. The general rule is that adopted children may inherit from or through their natural parents as well as their adopted parents. The exсeption to this rule occurs when the right to inherit from natural parents is divested. Whether the sons are entitled to inherit from David therefore depends on whether their right to inherit was divested when they were adopted in August 1961. This in turn depends on the meaning of the statutory phrase “except to the extent that inheritance rights have been divested by ... a final decree of adoption ... under the laws of this state or of any other jurisdiction.” 2
Both parties argue for different reasons that the statutory phrase “еxcept to the extent that inheritance rights have been divested by ... a final decree of adoption” means that the law in effect at the time of adoption has no bearing on whether adopted children may inherit from their natural parents. The sons argue that this statutory phrase means that a probate court in determining an intestate’s heirs may consider only the inheritance laws in effect at the time of the intestate’s death and the language of the adoption decreе, but may not consider other laws in effect at the time of the adoption unless the adoption decree incorporates these laws by reference.
Snelson argues that this statutory phrase means that a probate court in determining an intestate’s heirs after July 1977, when section 15-ll-109(l)(a) became effective, must conclude that adopted children are divested of the right to inherit from their natural parents regardless of the law in effect at the time of adoption. She bases this сonclusion on a reading of section 15-ll-109(l)(a) of the probate code in conjunction with section 19-3-608(1), 8B C.R.S. (1988 Supp.), and section 19 — 5— 104(4), 8B C.R.S. (1988 Supp.), of the children’s code. She contends that these statutes read in pari materia demonstrate a legislative intent to divest all adopted children of the right to inherit from a natural parent regardless of the law in effect at the time of adoption.
We find neither argument persuasive and hold that the right of adopted children to inherit from their natural parents depends оn the adoption and inheritance laws in effect at the time of adoption.
A.
We agree with the trial court and the court of appeals that the August 1961 adoption decrees did not expressly divest the sons of the right to inherit from David. The decrees ordered David to be “hereby divested of all legal rights and obligations in respect to [Alan and Gerald] and [Alan and Gerald] shall be free from all legal obligations of obedience and maintenance in respect to [David].” This language is virtually identical to section 4-1-11(2), the 1953 version of section 19-5-211(2), and described the legal effects of a final decree of adoption on the natural parents and the adopted children.

This language in the
B.
Regardless оf whether the language of the adoption decrees was sufficiently broad to incorporate by reference the law in effect in August 1961, however, we believe the intent of the General Assembly in enacting section 15-ll-109(l)(a) was to require a probate court to consider not only the language of the adoption decree but also the inheritance law in effect at the time of adoption. Our task in construing statutes is to ascertain and effectuate the intent of the General Assembly.
In re R.C.,
A plain reading of the phrase “except to the extent that inheritance rights have been divested by ... a final decree of adoption ... under the laws of this state or of any other jurisdiction” in section 15-11-109(l)(a) does not reveal what sources a probate court may consider in determining whether the right to inherit from natural parents has been lost. This language could be construed to prohibit the probate court from considering any source other than the language of the adoption decree, as the sons suggest. This language could also be construed to require the probate court to consider adoption laws in effect at the time of adoption as well as the language of the adoption decree but not the inheritance laws in effect at the time of adoption. Finally, this language could be construed to require the probate court to consider not only the adoption laws in effect at the time of adoption and the language of the adoption decree but also the inheritance laws in effect at the time of adoption. Because we conclude section 15-ll-109(l)(a) is susceptible to more than one interpretation, it is ambiguous.
1.
The legislative history of section 15 — 11— 109(1) is silent as to the sources a probate court may consider in determining whether inheritance rights of adopted children were divested. In construing the phrase “except to the extent that inheritance rights have been divested by a final order of relinquishment, a final decree of adoption, or an order terminating the parent-child relationship under the laws of this state or of any other jurisdiction,” however, we are guided by а number of rules of statutory construction.
The first applicable rule of construction is the “last antecedent rule.” This rule concerns whether the phrase “under the laws of this state or of any other jurisdiction” in section 15-ll-109(l)(a) can be construed to modify “a final decree of adoption” even though it immediately follows “an order terminating the parent-child relationship.” The last antecedent rule provides that in the absence of a contrary intention, referential and qualifying words and phrases refer solely to the clause immediately preceding it.
People v. McPherson,
When a referential or qualifying clause follows several words or phrases and is applicable as much to the first word or phrase as to the others in the list, however, the clause should be applied to all of the words or phrases that preceded it. 2A N. Singer,
Statutes and Statutory Construction
§ 47.33, at 245 (4th ed. 1984);
Board of Trustees of Santa Maria Joint Union High School Dist. v. Judge,
2.
Once we conclude that the phrase “under the laws of this state or of any other jurisdiction” in section 15-11-109(l)(a) modifies “a final decree of adoрtion,” two more rules of statutory construction come into play. First, a statute must be construed whenever possible to give effect to all of its parts. 2A N. Singer,
Statutes and Statutory Construction
§ 46.06, at 104 (4th ed. 1984);
Colorado Gen. Assembly v. Lamm,
With these rules in mind, we turn to the interpretations suggested by the parties.
3.
Construing section 15-ll-109(l)(a) to require a probate court to examine only the language of the adoption decree, as the sons suggest, gives no effect to the phrase “under the law of this state or of any other jurisdiction.” In addition, as the court of
Construing section 15-ll-109(l)(a) as divesting all adopted children of the right to inherit from natural parents who died intestate after July 1977 without regard to the law in effect at the time of adoption, as Snelson suggests, not only fails to give effect to the phrase “under the law of this state or of any other jurisdiction” but also fails to give effect to the phrase “except to the extent that.” To adopt the blanket rule Snelson suggests, we would have to rewrite the phrase “except to the extent that inheritance rights have been divested” in section 15-ll-109(l)(a) as “unless inheritance rights have been divested.”
Construing section 15-ll-109(l)(a) to require an examination of the laws in effect at the time of adoption, however, is a sensible reading of the statute because it gives effect to the phrase “under the laws of this state or of any other jurisdiction.” In addition, construing section 15-11-109(l)(a) to require an examination of the laws in effect at the time of adoption also gives meaning to the phrase “except to the extent” because laws in effect at different times may produce different results for adopted children depending on when the children were adopted and when the natural parent died. Children adopted between May 1961 and July 1977, for example, may not inherit by intestate succession from their natural parents who died before July 1977 because the inheritance law in effect at the time of the intestate’s death prohibited such a result. 1963 C.R.S. § 153-2-4;
People v. Estate of Murphy,
Children adopted after July 1977 also may not inherit by intestate succession from their natural parents who died thereafter. This result follows from a reading of section 15-ll-109(l)(a) together with section 19-11-108(1), 8 C.R.S. (1977), renumbered as § 19-3-608(1), 8B C.R.S. (1988 Supp.), a provision of thе children’s code enacted at the same time as section 15 — 11—109(l)(a). See ch. 248, sec. 1, § 19-11-108, 1977 Colo.Sess.Laws 1026, 1028. The 1977 version of section 19-3-608(1), which described the legal effect of an order terminating the parent-child relationship, stated:
An order for the termination of the parent-child legal relationship divests the child and the parent of all legal rights, powers, privileges, immunities, duties, and obligations with respect to each other, except for the right of the child to inherit from the parent. Such child’s right of inheritance shall be terminated only by a final decree of adoption.
(Emphasis added). That the effect of an adoption decree entered after section 15-ll-109(l)(a) became effective is to divest adopted children of the right to inherit from their natural parents finds additional support in section 19-4-103(4), 8 C.R.S. (1981), renumbered as § 19-5-104(4), 8B C.R.S. (1988 Supp.), a 1981 addition to the children’s code. See ch. 237, sec. 2, § 19-4-103(4), 1981 Colo.Sess.Laws 1045, 1046. The 1981 version of section 19-5-104(4), which described the legal effect of a final order of relinquishment, stated:
A final order of relinquishment shall divest the relinquishing parent or parents of all legal rights and obligations they may have with respect to the child relinquished, but it shall not modify the child’s status as an heir at law which shall cease only upon a subsequent final decree of adoption ....
When read in pari materia with what are now sections 19-3-608(1) and 19-5-104(4), section 15-ll-109(l)(a) also demonstrates a present legislative intent not to divest adopted children of the right to inherit by intestate succession from their natural parents during the interim period following an order terminating the parent-child relationship or order of relinquishment but preceding adoption. Such an interpretation of section 15-ll-109(l)(a) thereby gives further effect to the phrase “except to the extent that” because children would be divested of the right to inherit from their natural parents depending on whether they had been adopted.
C.
The difference between Bomareto and David can best be explained by interpreting section 15-ll-109(l)(a) to require a probate court to consider adoption and inheritance laws in effect at thе time of adoption. The distinction urged by the court of appeals in Bomareto is factually inaccurate. Both the adoption decree in Bomareto and the adoption decrees in David contained identical divesting language which incorporated the language of then-applicable section 4-1-11. The distinction urged by the majority of the court of appeals in David, however, properly recognizes that children adopted after May 1961, as the sons in this case were, could not inherit from their natural parents, because the inheritance law in effect at the time of their adoption divested them of this right.
Bomareto erroneously concluded that under section 15-ll-109(l)(a) a probate court could not consider adoption and inheritance laws in effect at the time of adoption unless they were incorporated by reference into the adoption decree, while David correctly concluded that under section 15-ll-109(l)(a), a probate court must consider the adoption and inheritance law in effect at the time of adoption. We therefore disapprove оf the reasoning in Bomareto.
III.
We conclude that the General Assembly in enacting section 15-ll-109(l)(a) intended to require a probate court determining the heirs of a natural father who died intestate to consider adoption and inheritance laws in effect at the time of the adoption. Because the inheritance law in effect at the time of the sons’ adoption prohibited adopted children from inheriting from or through their natural parents, the court of appeals correctly cоncluded that
The judgment of the court of appeals is affirmed.
Notes
. The court of appeals in
Bomareto
did not hold expressly that section 15 — 11—109(l)(a) permits an examination of the law in effect at the time of adoption only if incorporated into the adoption decree. This holding can be implied, however, from two facts. First, the court of appeals in
Bomareto
stated that the "dispositive question” was "whether this language [in the adoption decree] divested [the adopted child] of her right to inherit from her natural father.”
Bo-mareto,
. Neither the parties nor the court of appeals in David focused on the phrase "under the laws of this state or of any other jurisdiction.”
. Section 4-1-11(2) provided:
The natural parents shall be divested of all legal rights and obligations in respect to the foster child, and the adopted child shall be free from all legal obligations of obedience and maintenance in respect to the natural parents. Nothing herein contained shall be construed to divest any natural parent of any legal right or obligation where the adopting parent is a step-parent and is married to said natural parent.
This language remains substantially intact in section 19-4-113(2), 8B C.R.S. (1986), renumbered as % 19-5-211(2), 8B C.R.S. (1988 Supp.), which states that the natural parents "shall be divested of all legal rights and obligations with respect to the child, and the adopted child shall be free from all legal obligations of obedience and maintenance with respect to the natural parents.”
. Section 153-2-4(2), which was in effect when the sons were adopted, states:
Legally adopted children shall not inherit property from or through their natural parents or the heirs of their natural parents who die intestate after their adoption; provided, that a legally adopted child who was last adopted by the spouse of a natural parent shall inherit from and through such natural parents and the heirs of such natural parent.
