(D) Color blindness is an $X$-linked recessive disorder. Let the allele for normal vision be $X^C$ and the allele for color blindness be $X^c$.The genotype of a color-blind woman is $X^cX^c$.The genotype of a man with normal vision is $X^CY$.When these two individuals cross:Parents: $X^cX^c$ (female) $	imes$ $X^CY$ (male)Gametes: $X^c$ and $X^c$ (from mother); $X^C$ and $Y$ (from father)Offspring genotypes:$X^CX^c$ (Carrier daughter, normal vision)$X^CX^c$ (Carrier daughter, normal vision)$X^cY$ (Color-blind son)$X^cY$ (Color-blind son)Therefore, all sons will be color-blind, and all daughters will be carriers with normal vision.
