Consider two hypothetical genes, Aand B. A codes for the trait plant pigment where aa individuals lack all pigment. Gene B codes for bent leaf trait where bb individuals have bent leaves. In the following cross between a heterozygotewith normal plant pigment and straight leavesand homozygousrecessive with no pigment and bent leaves what phenotypic ratios would be attained in the following situations.
(A) AaBb x aabb a. The A and B genes are on separate chromosomes
(B) The A and B genes are on the same chromosomes, but are so close that recombination never occurs between A and B.
(C) The A and B genes are on the same chromosomes, but are so far apart that recombination always occurs between A and B.
(D) The A and B genes are linked on the same chromosomes 10 map units apart.
(E) The A and B genes are linked on the same chromosomes 5 map units apart.
