(2) But if crossovers occur in between the two genes during meiosis, then the heterozygous parent will generate all four possible gametes: GW, gw, Gw and gW, and we will see all four offspring phenotypes, perhaps: 45% of the offspring yellow and round (GW/gw), 45% of the offspring green and wrinkle ...
