Homozygous

Detailed explanation-1: -The presence of two different alleles at a particular gene locus. A heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles (compound heterozygote).
Detailed explanation-2: -Heterozygous refers to having different alleles for a particular trait. If the two versions are different, you have a heterozygous genotype for that gene. The relationship between the two alleles affects which traits are expressed.
Detailed explanation-3: -An individual that contains two different alleles of a gene is heterozygous.
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: -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.
