(C) Colour blindness is an $X$-linked recessive disorder. Let the allele for normal vision be $X$ and the allele for colour blindness be $X^c$.$A$ colour blind female has the genotype $X^cX^c$.$A$ normal male has the genotype $XY$.When they cross $(X^cX^c 	imes XY)$:- The female produces gametes $X^c$ and $X^c$.- The male produces gametes $X$ and $Y$.The resulting offspring genotypes are:- $X^cX$ (Carrier daughter)- $X^cY$ (Colour blind son)Therefore,all daughters will be carriers and all sons will be colour blind.
