Detailed explanation-1: -Definition. Homozygous, as related to genetics, refers to having inherited the same versions (alleles) of a genomic marker from each biological parent. Thus, an individual who is homozygous for a genomic marker has two identical versions of that marker.

Detailed explanation-2: -If the two alleles are the same, the individual is homozygous for that allele. If the alleles are different, the individual is heterozygous.

Detailed explanation-3: -Genotypes are described as homozygous if there are two identical alleles at a particular locus and as heterozygous if the two alleles differ. Alleles contribute to the organism’s phenotype, which is the outward appearance of the organism.

Detailed explanation-4: -If an organism has two copies of the same allele, for example AA or aa, it is homozygous for that trait. If the organism has one copy of two different alleles, for example Aa, it is heterozygous.
