het·er·o·zy·gous

(het'ĕr-ō-zī'gŭs),
Having different alleles at a given locus on the pair of chromosomes present in the diploid state; for example, having a normal beta globin gene (coding for normal hemoglobin, Hb A) at locus p15.5 on one chromosome 11 and an abnormal gene (coding for sickle-cell hemoglobin, Hb S) at the same locus on the other chromosome 11.

heterozygous

(hĕt′ər-ə-zī′gəs)
adj.
1. Having different alleles at one or more corresponding chromosomal loci.
2. Of or relating to a heterozygote.

het·er·o·zy·gous

(het'ĕr-ō-zī'gŭs)
Having different allelic genes at one locus or (by extension) many loci; heterotic.

heterozygous

Of a person carrying different genes at the same gene locus in corresponding chromosomes. The ALLELES are different. A single DOMINANT gene can manifest itself in a heterozygous person. Recessive genes are only manifest if both are present (HOMOZYGOUS).

Heterozygous

Two different genes controlling a specified inherited trait.
