- (1) An "outline slightly defined" (AA quality) yolk is a yolk outline that is indistinctly indicated and appears to blend into the surrounding white as the egg is twirled.
- (2) An "outline fairly well defined" (A quality) yolk is a yolk outline that is discernable but not clearly outlined as the egg is twirled.
- (3) An "outline well defined" (B quality) yolk is a yolk outline that is quite definite and distinct as the egg is twirled.
- (4) An "outline plainly visible" (C quality) yolk is a yolk outline that is clearly visible as a dark shadow when the egg is twirled.
- (5) A "slightly enlarged and slightly flattened" (B quality) yolk is a yolk in which the yolk membranes and tissues have weakened somewhat causing it to appear slightly enlarged and slightly flattened.
- (6) An "enlarged and flattened" (C quality) yolk is a yolk in which the yolk membranes and tissues have weakened and moisture has been absorbed from the white to such an extent that it appears definitely enlarged and flat.
- (7) A "practically free from defects" (AA or A quality) yolk is a yolk that shows no germ development but may show other very slight defects on its surface.
- (8) A "definite but not serious defects" (B quality) yolk is a yolk that may show definite spots or areas on its surface but with only slight indication of germ development or other pronounced or serious defects.
- (9) An "other serious defects" (C quality) yolk is a yolk that shows well developed spots or areas and other serious defects, such as olive yolks, which do not render the egg inedible.
- (10) A "clearly visible germ development" (C quality) yolk is a yolk in which the development of the germ spot of a fertile egg that has progressed to a point where it is plainly visible as a definite circular area or spot with no blood in evidence.
- (11) "Blood due to germ development" is blood caused by development of the germ in a fertile egg to the point where it is visible as definite lines or as a blood ring. Such an egg is classified as inedible.
