Explanation:
Detailed explanation-1: -Every person has two copies of each gene, one inherited from each parent. Most genes are the same in all people, but a small number of genes (less than 1 percent of the total) are slightly different between people. Alleles are forms of the same gene with small differences in their sequence of DNA bases.
Detailed explanation-2: -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.”
