And in this particular case, because we're dealing with a homozygous dominant tall plant, we have uppercase T, uppercase T, where T stands for tall and G stands for green. Now, what about parent number two? Let's suppose we have a second P plant, but this p plant is homozygous recessive for both of those traits. So that means we have a purely yellow and a purely short plant. So if we examine these two homologous chromosome pairs, this one basically carries the allele. So we have allele number one and allele number two.
