Vedclass · Answer

(B) Hemophilia is an $X$-linked recessive disorder. Let $X^H$ be the normal allele and $X^h$ be the hemophilic allele.Since the father is normal,his genotype is $X^H Y$.If the mother is a carrier $(X^H X^h)$,the cross is $X^H Y 	imes X^H X^h$.The offspring genotypes will be $X^H X^H$ (normal female),$X^H X^h$ (carrier female),$X^H Y$ (normal male),and $X^h Y$ (hemophilic male).If the mother is normal $(X^H X^H)$,all children will be normal.However,in the context of standard genetics problems where a trait is being analyzed,if we assume the mother is a carrier,the male children have a $50\%$ chance of inheriting the $X^h$ chromosome from the mother and the $Y$ chromosome from the father,resulting in hemophilia $(X^h Y)$.
