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: -Organisms that have two identical alleles for a particular trait are said to be homozygous.

Detailed explanation-3: -Homozygous 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-4: -Having two identical alleles for a given gene is called homozygous. This means that a pair of identical dominant alleles or recessive alleles are found in the same genetic locus of a chromosome. Additionally, an individual that expresses a recessive trait is always homozygous for that gene.
