None of the above

Explanation:
Detailed explanation-1: -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: -We all have two alleles, or versions, of each gene. Being homozygous for a particular gene means you inherited two identical versions. It’s the opposite of a heterozygous genotype, where the alleles are different. People who have recessive traits, like blue eyes or red hair, are always homozygous for that gene.
Detailed explanation-3: -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.
