Children with phenylketonuria (PKU) are provided with a diet low in phenylalanine in order to:
A) modify their phenotype with diet
B) modify their genotype with diet
C) modify their dominant genes with diet
D) modify their recessive genes with diet

Question

Quizplus · Accepted Answer

PKU is an autosomal recessive genetic disorder that affects the ability of the body to process phenylalanine. People with PKU lack the enzyme needed to break down this amino acid, which can accumulate in the body and cause intellectual disability and other health problems. A low-phenylalanine diet is the primary treatment for PKU because it helps to reduce the amount of phenylalanine in the body and prevent the associated health problems. However, the diet does not modify the genotype or genes of the affected individual, only their phenotype (observable traits).
