And if we examine the chromosomes, remember, in any diploid organism, such as the p plant, every single chromosome has a homologous chromosome that carries a gene that codes for that same trait. And so we have two of these pairs of homologous chromosome, pair number one and pair number two. Now, this pair of homologous chromosomes basically carry the two genes, the two alleles that code for the color. And in this particular case, because we're dealing with the dominant color, we have uppercase G, uppercase G that designates the color green. Likewise, if we examine the second pair of homologous chromosomes, we have allele number one and we have allele number two. And each one of these alleles basically is a segment of DNA that codes for protein, that expresses our hydrate.
