Vedclass · Answer

(C) Phenylketonuria $(PKU)$ is an inborn error of metabolism that is inherited as an autosomal recessive trait.It is caused by a mutation in the gene that codes for the enzyme phenylalanine hydroxylase.This single gene mutation leads to multiple phenotypic effects,including mental retardation,reduction in hair pigmentation,and skin problems.Since a single gene influences multiple phenotypic traits,this is a classic example of pleiotropy.
