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.
