Detailed explanation-1: -A heterozygous individual has two different alleles. Therefore it would have the genotype Aa. An individual with the genotype Aa can make two types of gametes: A and a. Since this is a random process, the individual will, on average, make equal numbers of each gamete.
Detailed explanation-2: -Hh genotype will also produce two gametes in which one gamete has an “H” allele and the other gamete has an “h” allele.
Detailed explanation-3: -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-4: -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.
