ho·mo·zy·gous

(hō'mō-zī'gŭs),
Having identical alleles at one or more loci.

homozygous

(hō′mō-zī′gəs, -mə-, hŏm′ə-)
adj.
Having the same alleles at a particular gene locus on homologous chromosomes.

ho′mo·zy·gos′i·ty (-gŏs′ĭ-tē) n.

homozygous

[hō′məzī′gəs]
Etymology: Gk, homos + zygon, yoke
having two identical alleles at corresponding loci on homologous chromosomes. An individual who is homozygous for a trait has inherited from each parent one allele for that trait. A person who is homozygous for a genetic disease caused by a pair of recessive alleles, such as sickle cell anemia, manifests the disorder. All of his or her offspring will inherit the allele for the disease. Compare heterozygous.

ho·mo·zy·gous

(hō'mō-zī'gŭs)
Having identical genes at one or more loci.

homozygous

Having identical gene pairs (ALLELES) at corresponding positions (loci) on the chromosome pairs. People who are homozygous for a quality or condition will always manifest it.

Homozygous

Identical genes controlling a specified inherited trait.

homozygous

expression of inheritance of genetic disease, where the individual inherits the causative gene from both parents and expresses overt disease (see heterozygous)

ho·mo·zy·gous

(hō'mō-zī'gŭs)
Having identical alleles at one or more loci.

homozygous (hō´mōzī´gus),

adj a term indicating that genes lying at equivalent loci on chromosome pairs are the same.

homozygous

having the characteristic of homozygosity.
