Phenylketonuria (PKU) is an autosomal recessive disorder due to the deficiency of the enzyme phenylalanine hydroxylase. This leads to the failure in converting phenylalanine to ... WebPhenylketonuria (PKU) is a rare metabolic disorder. Children with PKU can’t process an amino acid called phenylalanine. Phenylalanine is in many common foods. It helps the body make protein. It's also important for brain growth. It's normally changed to tyrosine, which helps create all of the body's proteins.

WebMendel's Laws of Heredity are usually stated as: 1) The Law of Segregation: Each inherited trait is defined by a gene pair. Parental genes are randomly separated to the sex cells so that sex cells contain only one gene of the pair. Offspring therefore inherit one genetic allele from each parent when sex cells unite in fertilization.
