Detailed explanation-1: -An individual inherits two alleles, one from each parent, for any given genomic location where such variation exists. 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-2: -(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-3: -An individual that contains two different alleles of a gene is heterozygous.

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.

Detailed explanation-5: -Homozygous (and its less common form homozygotic) means “relating to a cell that has two identical alleles for a particular gene at corresponding positions on homologous chromosomes.”
