Detailed explanation-1: -Genotypes are described as homozygous if there are two identical alleles at a particular locus and as heterozygous if the two alleles differ.
Detailed explanation-2: -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-3: -(HOH-moh-ZY-gus JEE-noh-tipe) 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-4: -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-5: -You either have two dominant alleles (homozygous dominant) or two recessive alleles (homozygous recessive).
