Question

Phenylketonuria is an inborn error of metabolism that is inherited as (1)Autosomal recessive trait (2)Sex-linked dominant trait (3)X-linked recessive trait (4)Autosomal dominant trait

Answer 1

Answer:

Autosomal Recessive Trait

Explanation:

In this case since both parents would have to have one PKU  gene and one normal gene they show no signs or symptoms of PKU. However since the offspring would inherit one gene from either parent, it would become the dominant gene in the offspring and therefore the offspring would show signs and symptoms of Phenylketonuria.
