In a dihybrid cross (2 sets of alleles, independently assorted) each parent(heterozygous for both traits) can have 4 combinations of alleles in theirgametes), so to calculate the odds for inheritance of particular geneticcombinations, we must draw out 16 squares. In the case of our purple/yellowand starchy/sweet corn kernels, we can calculate the odds of the possiblephenotypes. Purple & starchy: purple & sweet: yellow & starchy: yellow &sweet, can be calculated asO 9:2:2:39:3;3;1O 5:4:4:3

A Dihybrid cross is a cross between two organisms with two different traits. It involves two different genes. A gene consists of two alleles. Here, two corn plants are taken. One is purple(PP) and has starchy corns(SS). Another one is yellow(pp) and has sweet corns(ss). Both are crossed and the result is shown in the punnet square.
