Explanation:
Detailed explanation-1: -The presence of two identical alleles at a particular gene locus. A homozygous genotype may include two normal alleles or two alleles that have the same variant.
Detailed explanation-2: -When the loci in the matching chromosomes bear the same alleles, it is described as homozygous. It means that the alleles code for the same trait. A ‘homozygous’ organism for a particular trait is described to possess either a pair of dominant alleles (e.g. AA) or a pair of recessive alleles (e.g. aa).
