Vedclass · Answer

(C) Colour blindness is an $X$-linked recessive disorder.$1$. The man's father was colour blind,but the man himself is normal because he inherits his $Y$ chromosome from his father and his $X$ chromosome from his mother. Thus,the man's genotype is $XY$.$2$. The woman had a colour blind mother $(X^cX^c)$ and a normal father $(XY)$. She must have inherited an $X^c$ chromosome from her mother and an $X$ chromosome from her father. Thus,the woman's genotype is $X^cX$.$3$. Cross: $XY 	imes X^cX$- Offspring genotypes: $XX, X^cX, XY, X^cY$- The male children are $XY$ (normal) and $X^cY$ (colour blind).$4$. Out of the male children,$50\%$ are colour blind.

$A$ man whose father was colour blind marries a woman who had a colour blind mother and normal father. What percentage of male children of this couple will be colour blind (in $\%$)?
