They carry similar genes that code for proteins that express the same type of trade. So in this particular case, we have the genes uppercase G and lowercase G that express the same type of trade, the color trades. And in this case, we have these two genes that are homologous. And what that means is they code for protein that expresses the same type of trait. In this case, the high traits. So we have one homologous chromosome pair, a second homologous chromosome pair.
