C) All AaBb
D) All AABB

When Mendel crossed AABB with aabb individuals, all the F1 generations will be AaBb. This is because each parent contributes one allele per gene, resulting in all offspring having one dominant allele (A or B) and one recessive allele (a or b). Therefore, the genotypic ratio of the F₁ generation will be 100% AaBb.
