All the possible allele combinations from the gametes of an organism with the genotype AaBb would be AB, Ab, aB, and ab.
The allele combination for a dihybrid genotype would be a simple cross of the two alleles for the two genes.
In this case, the two genes are Aa and Bb
Aa x Bb
AB Ab aB ab
Thus, the gametes would have the alleles AB, Ab, aB, and ab.
