Explanation:
Detailed explanation-1: -When an organism has two of the same alleles for a specific gene, it is homozygous (homo means “same") for that gene. An organism can be either homozygous dominant (TT) or homozygous recessive (tt). If an organism has two different alleles (Tt) for a certain gene, it is known as heterozygous (hetero means different).
Detailed explanation-2: -[Capital letters signify the dominant trait, and small letters represent the recessive trait.] RR – meaning a homozygous with both dominant alleles for a trait. rr – meaning-a homozygous with both recessive alleles for a trait.
