The following terms define the condition of the yolk in determining the quality of individual eggs:

1. (1) "Outline slightly defined," (AAquality) a yolk outline that is not distinctly indicated and appears to blend into surrounding white as the egg is twirled;
2. (2) "Outline fairly well defined," (Aquality) a yolk outline that is discernible but not clearly outlined as the egg is twirled;
3. (3) "Outline plainly visible," (Bquality) a yolk outline that is clearly visible as a dark shadow when the egg is twirled;
4. (4) "Enlarged and flattened," (Bquality) 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;
5. (5) "Practically free from defects," (AAorAquality) a yolk that shows no germ development but may show other very slight defects on its surface;
6. (6) "Serious defects," (Bquality) a yolk that shows well developed spots or areas and other serious defects, such as olive yolks, which do not render the egg inedible;
7. (7) "Clearly visible germ development," (Bquality) a development of the germ spot on the yolk 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;
8. (8) "Blood due to germ development," 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.
