Solution
The correct answer is "AaBb x aabb".
A testcross is a way to explore the genotype of an organism. It involves breeding the organism in question with another organism who has a homozygous recessive genotype for the traits in question. In this case, "AaBb x aabb" is the only option that involves breeding with a homozygous recessive organism ("aabb").
