Now, this produces two types of gametes, and this also produces two types of gametes. So let's suppose that this individual is the male individual and this individual is the female individual. So let's say that this is basically our sperm cells and these are our excel. So when this sperm cell combines with this excel, we produce a true breeding red color. When this mates with this, we produce a heterozygous individual. When this mates with this, we once again produce a heterozygous individual.
