(C) Color blindness is an $X$-linked recessive trait. Let $X^c$ represent the allele for color blindness and $X$ represent the normal allele.The genotype of a color-blind woman is $X^cX^c$.The genotype of a normal-vision man is $XY$.When these parents produce offspring:- The mother contributes an $X^c$ chromosome to all her children.- The father contributes an $X$ chromosome to his daughters and a $Y$ chromosome to his sons.Cross: $X^cX^c 	imes XY$- Daughters: $X^cX$ (Carrier,normal vision)- Sons: $X^cY$ (Color-blind)Therefore,all sons will be color-blind and all daughters will be carriers with normal vision.

What is the phenotype of the offspring of a color-blind woman and a normal-vision man?
