What is true about the following genotype : A B a b? Select all of the correct answers (check all that apply) the allelic configuration is repulsion (trans) a gamete made by this individual that contains a and b would be considered nonrecombinant (parental ) a gamete made by this individual that contains A and b would be considered nonrecombinant ( parental ) the allelic configuration is coupling (cis)

In a test-cross between an individual who is AaBb and an individual who is aabb, the following types and numbers of offspring were obtained: 22 AaBb 67 Aabb 70 aaBb 21 aabb Which of the following is true? A. The A and B alleles in the AaBb parent are present in repulsion. B. The A and B genes are linked to each other and are 43 cM apart. C. It is possible that the two genes are present on different chromosomes. D. The recombinant gametes from the double heterozygote are Ab and aB.

Questions 7-12 deal with 2 unlinked genes, A and B. From an A/a; B/b organism, which line shows correct genotypes for 4 sperm that could be produced by a single germ cell that segregated its chromosomes normally. You can ignore the effects of recombination.
