Since genotype TtYy is heterozygous for two genes i.e. it has both dominant and recessive alleles of two genes, it will form total four types of gametes.
The presence of two different alleles at a particular gene locus. A heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles (compound heterozygote).
People with genotypes AA and aa are homozygotes, which means they have two copies of the same allele. Individuals with genotype Aa have two different alleles at the A locus, i.e., they have two different alleles at the A locus.
You have a heterozygous genotype for that gene if the two versions differ. Being heterozygous for hair color, for example, means you have one allele for red hair and one allele for brown hair. The interaction of the two alleles influences which traits are expressed.
