homozygote [¦hō·mə′zī‚gōt]
(genetics)
An individual who has identical alleles at one or more loci and therefore produces identical gametes with respect to these loci.

Homozygote 

a cell or an organism in whose genetic makeup the homologous chromosomes carry the identical form of a given gene. A homozygote originates during the fusion of gametes that are identical for a given gene. The genetic formula of a diploid organism homozygous for allele A or a can be written in the form AA or aa; for a triploid organism, AAA or aaa; and so forth.

This trend remains significant between the D allele carriers and II homozygotes in female endurance athletes (MDA) as well (p = 0.
Allozyme genetic studies of bivalves have often revealed significant deficiencies of heterozygotes relative to the Hardy-Weinberg model and a number of explanations were proposed such as selection, the Wahlund effect, inbreeding and null alleles where the presence of nonfunctional protein product confuses the scoring of heterozygotes and homozygotes (Gaffney 1994).
Although heterozygotic carriers of certain alleles might enjoy elevated IQs, homozygotes could be stricken with terrible diseases like Tay-Sachs, which kills mercilessly during early childhood.
