Vedclass · Answer

(C) Hemophilia is an $X$-linked recessive disorder.Let $X^h$ represent the chromosome carrying the hemophilia gene and $X$ represent the normal chromosome.$A$ hemophilic woman has the genotype $X^hX^h$.$A$ normal man has the genotype $XY$.When they cross: $X^hX^h 	imes XY$.The possible genotypes of the offspring are:$1$. $X^hX$ (Carrier daughter)$2$. $X^hY$ (Hemophilic son)Thus,all daughters will be carriers (phenotypically normal) and all sons will be hemophilic.Therefore,all sons are hemophilic.

If a hemophilic woman marries a normal man,what will be the theoretical ratio of their offspring regarding hemophilia?
