The father and son in the family are brown-eyed hemopholics, and the mother has normal blood
The father and son in the family are brown-eyed hemopholics, and the mother has normal blood clotting and blue eyes. Can we say that the son inherited all his traits from his father?
Mother – aaXGX? Father – A? XgY Son – AaXgY. Since the disease gene is linked to the sex X chromosome, the son inherited the Y chromosome from his father, which is responsible for sex and does not carry genes responsible for blood clotting, and from his mother he received an X with the hemophilia g gene. Consequently, the mother’s genotype is aaXGXg and she is the carrier of this disease. The son’s phenotype was the result of the fusion of the following parents from among the possible gametes: aXg – from the mother, AY – from the father. So the son inherited the disease from his mother, and the color of his eyes from his father.
