Aabb for dihybrid crosses, need to figure out the total possible. Cross two heterozygous tall black cows. Assuming all heterozygous traits in both parents, and one allele is dominant over the other, then there will be 4 genotypes and 2 phenotypes in monohybrid offspring if all this is true, then we can figure out the odds of what their offspring will be by using a 4×4 punnett square. Includes worked examples of dihybrid crosses.

We call this a dihybrid cross.

First let us use a punnett square to examine the theoretical outcome of the heterozygous x heterozygous dihybrid cross. This punnett square represents a cross between two pea plants that are heterozygous for two characteristics.

Punnett squares are one method for visually demonstrating the probability of offspring genotypes and offspring phenotypes. Assuming all heterozygous traits in both parents, and one allele is dominant over the other, then there will be 4 genotypes and 2 phenotypes in monohybrid offspring if all this is true, then we can figure out the odds of what their offspring will be by using a 4×4 punnett square.
