Vedclass · Answer

(D) Color blindness is an $X$-linked recessive disorder. Let $X^c$ represent the allele for color blindness and $X$ represent the normal allele.For a daughter to be color-blind,her genotype must be $X^c X^c$.She receives one $X^c$ chromosome from her mother and one $X^c$ chromosome from her father.Therefore,the father must be color-blind $(X^c Y)$ and the mother must be either a carrier $(X X^c)$ or color-blind $(X^c X^c)$.Among the given options,the condition where the mother is a carrier $(X X^c)$ and the father is color-blind $(X^c Y)$ allows for the birth of a color-blind daughter $(X^c X^c)$.
