Question

If a man who is not color-blind (x-linked recessive trait) marries a color-blind woman, is there any chance of them having a son who is not color-blind? Show the cross and EXPLAIN the answer Color blind (c) Normal vision (C)

Answer 1

if a mother is a carrier for colorblindness (X+Xc), and a father has normal vision X+Y, then their sons have a 50% chance of colorblindness because they inherit their X chromosome from their mother and their Y chromosome from their father.
