Heterozygote

a cell or organism having in its hereditary set (genotype) different forms (alleles) of a given gene.

A heterozygote is the result of the union of gametes of different genetic composition, each of which brings its own alleles to the zygote. For example, homozygous types AA and aa form gametes A and a respectively. The heterozygote obtained by the hybridization of AA and aa always forms mixed gametes (A and a). Crossing this type with itself or with the recessive parental type aa produces offspring of two types—phenotypic A and phenotypic a. The splitting of the heterozygote proceeds according to Mendel’s law. The preservation of the heterozygote is of significance in agriculture, since splitting often leads to the loss of valuable qualities. Almost all fruit trees are heterozygous; in order to avert splitting and the loss of valuable traits, they are bred by vegetative reproduction, apomixis, gynogenesis, or parthenogenesis.

heterozygote

an individual containing two different allelic forms of the same gene in all DIPLOID (1) cells. Thus if gene A has two alleles, A₁ and A ₂, the heterozygote would contain both alleles (A 1/A 2). Compare HOMOZYGOTE.
