Detailed explanation-1: -A homozygous genotype contains two identical alleles. An individual can either be homozygous dominant (ex: HH) or homozygous recessive (ex: hh). A heterozygous genotype contains two different alleles (ex: Hh).

Detailed explanation-2: -Conventions and terms used in explaining genetic problems Dominant alleles are written as a capital letter (H), and recessive alleles as a small (lower case) version (h) of the same letter. whereas one with two different forms (Hh) is called heterozygous (a heterozygote)-also called a hybrid.

Detailed explanation-3: -A full head of hair is a dominant feature, with the homozygous gene of HH.

Detailed explanation-4: -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.
