Question

Offspring inherit _________________; if one or both parents passes on a gene with DNA that does not code for functional proteins, disorders like phenylketonuria can result.

Answer 1

Offspring inherit one copy of each gene from both parents if one or both parents passes on a gene with DNA that does not code for functional proteins, disorders like phenylketonuria can result.

How do parents pass on one copy of each gene to their children?

Their mother passes one copy on to them through the egg, while their father passes the other one along (via the sperm). Each egg and sperm have a single set of 23 chromosomes. Two copies of each chromosome and two copies of each gene are present when the sperm fertilizes the egg, resulting in the formation of an embryo.

An autosomal recessive metabolic genetic condition called phenylketonuria (PKU) is defined by a mutation that renders the gene for the hepatic enzyme phenylalanine hydroxylase (PAH) inactive.
