Young chickens have no noticeable gender differences, but it is economically feasible to set different feeding regimes for future males and hens. It is known that the gene that determines the color of plumage is localized on the X chromosome, with pockmarked color dominating over white, and the difference between the colors is noticeable immediately after hatching. What crosses should be put in order to immediately divide the hatched chickens on the floor?
If females are heterogametic in females, then in general terms the genotype can be represented as follows:
XX – determines the male gender – cock.
XY – defines the female gender – chicken.
Since the color gene is located on the X chromosome, and it is present in both sexes, it is impossible to distinguish roosters and hens by color.
