Question

Унекоторых кур белая и коричневая окраска перьев определяется парой генов, сцепленных с полом. Ген белых перьев доминирует над коричневым. Можно ли отличить пол цыплят по окраске их перьев, если скрестить коричневую курицу и белого петуха?

Answer 1

Нет, нельзя. могут получится коричневые петухи белые курочки

Answer 2

Can the sex of chicks be determined by the color of their feathers if a brown hen and a white rooster are crossed?

Yes, it is possible to determine the sex of chicks based on the color of their feathers when a brown hen and a white rooster are crossed. The color of feathers in chickens is determined by a pair of genes that are linked to the sex of the bird. The gene for white feathers is dominant over the gene for brown feathers.

When a brown hen and a white rooster are crossed, the offspring will inherit one gene for feather color from each parent. Since the gene for white feathers is dominant, chicks that inherit at least one copy of the white feather gene will have white feathers, while chicks that inherit two copies of the brown feather gene will have brown feathers.

However, it is important to note that the color of feathers alone cannot definitively determine the sex of chicks. Feather color is just one of many factors that can be used to determine the sex of chickens. Other methods, such as examining physical characteristics or DNA testing, may be more accurate in determining the sex of chicks.
