In a dihybrid cross (2 sets of alleles, independently assorted) each parent (heterozygous for both traits) can have 4 combinations of alleles in their gametes), so to calculate the odds for inheritance of particular genetic combinations, we must draw out 16 squares. In the case of our purple/yellow and starchy/sweet corn kernels, we can calculate the odds of the possible phenotypes. Purple & starchy: purple & sweet: yellow & starchy: yellow & sweet, can be calculated as 9:2:2:3 9:3:3;1 5:4:4:3
