Definition of Homozygote Homozygote: A person who has two
identical forms of a particular gene, one inherited from each
parent. For example, a girl who is a homozygote for cystic
fibrosis (CF) received the cystic fibrosis gene from both of her
parents and therefore has cystic fibrosis. The opposite of a
homozygote is a heterozygote, a person who has two different
forms of a particular gene. For example, the father and mother
of a cystic fibrosis child are heterozygotes for cystic fibrosis
(CF). Each carries one normal gene and one cystic fibrosis gene
but has no signs or symptoms of the disease.Source: MedTerms™
