(B) i. Color blindness is an $X$-linked recessive disorder.ii. $A$ son receives his $X$ chromosome from his mother and his $Y$ chromosome from his father.iii. Since the woman has normal vision but has colorblind children,she must be a carrier $(X^C X^c)$.iv. For a daughter to be colorblind $(X^c X^c)$,she must inherit one recessive allele from each parent. Since the mother is a carrier $(X^C X^c)$,the father must be colorblind $(X^c Y)$ to pass the recessive allele to his daughter.v. Therefore,the genotype of the woman is $X^C X^c$ and the genotype of her husband is $X^c Y$.

$A$ woman has normal vision but some of her sons and daughters are colorblind. What will be the genotype of the woman and her husband?
