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: -Homozygous: You inherit the same version of the gene from each parent, so you have two matching genes. Heterozygous: You inherit a different version of a gene from each parent. They do not match.

Detailed explanation-3: -What is it? Homozygous, or homozygosity, refers to the inheritance of genes from each biological parent. The variant results from a mutation that changes the DNA sequence making up a gene. Experts refer to variations in genes as alleles. If the alleles are identical, a person is homozygous for that gene.

Detailed explanation-4: -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.”

Detailed explanation-5: -When true-breeding, or homozygous, individuals that differ for a certain trait are crossed, all of the offspring will be heterozygous for that trait. If the traits are inherited as dominant and recessive, the F1 offspring will all exhibit the same phenotype as the parent homozygous for the dominant trait.
