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. And when this sperm cell combines with this Xcel, we produce a homozygous white individual. So we see that 25% are homozygous red. 50% are heterozygous pink because two fourths so one two out of four are heterozygous pink, and one fourth so 25% are homozygous white.
