(Drаw chrоmоsоmes on а piece of pаper) Two different genes are linked on the same chromosome. Let the letters A and B represent these two genes. Each gene comes with two alleles. The A allele is dominant to the a allele, and the B allele is dominant to the b allele. An aaBB individual is crossed to an AAbb individual to produce F1 AaBb offspring. The AaBb offspring are then crossed to aabb individuals to produce an F2 generation. What are the genotypes of the F2 recombinant offspring?
