Vedclass · Answer

(B) Sex-linked disorders are caused by mutations in genes located on the sex chromosomes ($X$ or $Y$).Most sex-linked disorders,such as hemophilia and color blindness,are $X$-linked recessive.In these cases,the disorder only manifests in the phenotype if the individual does not possess a functional dominant allele to mask the recessive mutation.Because males have only one $X$ chromosome (hemizygous),they are more frequently affected by $X$-linked recessive disorders than females,who have two $X$ chromosomes and can be carriers.
