Vedclass · Answer

(B) Hemophilia is a $X$-linked recessive genetic disorder.In this condition,the gene responsible for the clotting factor is located on the $X$ chromosome.Since it is recessive,a female must have the mutation on both $X$ chromosomes to express the disease,whereas a male only needs one mutated $X$ chromosome because he has only one $X$ chromosome ($XY$ genotype).Therefore,it is classified as a sex-linked recessive disorder.
