The gene for color blindness is recessive and located on the $X$ chromosome.

Vedclass · Answer

(B) Color blindness is a sex-linked recessive disorder caused by a mutation in genes located on the $X$ chromosome.Since males have only one $X$ chromosome $(XY)$,a single recessive allele is sufficient to express the trait.Females have two $X$ chromosomes $(XX)$,so they only express the trait if they are homozygous recessive $(X^cX^c)$.If a female has one recessive allele,she acts as a carrier $(X^cX)$ and does not show the symptoms.

Color blindness is generally observed in males. Why?
