On these chromosomes lie genes that also come in pairs; one each from our mothers and fathers. Each member of the gene pair is called an allele so each gene has two alleles or two allelic forms.

• A person who is homozygous for a mutation has two identical alleles for that gene. Both his/her parents passed along the same form of the gene.

• A person who is heterozygous for a mutation has two different alleles for the gene. His/her parents had different forms of the gene that was passed down.
