?Pronunciation: /ˌhoʊmoʊˈzaɪgəs ˈʤɛnəˌtaɪp/
homozygous genotype
Definition
A term that describes having two identical versions of the same gene (one inherited from the mother and one inherited from the father). In a homozygous genotype, either both genes are normal or both genes have the same mutation (change). For example, a person who inherits the same mutation in both copies of the LDLR gene is homozygous for that gene and will develop a severe form of familial hypercholesterolemia (very high levels of cholesterol in the blood).
