Question

In humans, colorblindness is a recessive, sex-linked trait. What is the probability

that the children of a woman heterozygous for colorblindness and a man with
normal color vision will be colorblind?

Answer 1

Step-by-step explanation:

Taking Xx as heterozygous and XX for normal

Woman =Xx Man =XX

all possible outcomes are XX, XX, XX and Xx

there is 0 probability of having a colorblind child

(But there is a 25 % chance that the child may be a carrier like its mother)
