Detailed explanation-1: -A homozygote is “an organism with identical pairs of genes with respect to any given pair of hereditary characters, and therefore breeding true for that character.” In other words, it’s an organism that has two copies of the same allele for a particular trait.

Detailed explanation-2: -We inherit half of our genes (alleles) from ma, & the other half from pa, so we end up with two alleles for every trait in our phenotype. An excellent example of multiple allele inheritance is human blood type. Blood type exists as four possible phenotypes: A, B, AB, & O.

Detailed explanation-3: -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: -Homozygous examples You can have brown eyes whether you’re homozygous (two alleles for brown eyes) or heterozygous (one for brown and one for blue). This is unlike the allele for blue eyes, which is recessive. You need two identical blue eye alleles in order to have blue eyes.
