Given the inheritance pattern of coat color in rats described in Problem 8, predict the genotype and phenotype of the parents that produced the following F1 offspring: a) 9/16 gray: 3/16 yellow: 3/16 black: 1/16 cream. b) 9/16 gray: 3/16 yellow: 4/16 albino. c) 27/64 gray: 16/64 albino: 9/64 yellow: 9/64 black: 3/64 cream. d) 3/8 black: 3/8 cream:2/8 albino. e) 3/8 black: 4/8 albino: 1/8 cream. The following genotypes of two independently assorting autosomal genes determine coat color in rats: A-B (gray) A-bb (yellow) aaB (black) aabb (cream)A third gene pair on a separate autosome determines whether any color will be produced. The CC and Cc genotypes allow color according to the expression of the A and B alleles. However, the cc genotype results in albino rats regardless of the A and B alleles present. A. AAbbCC * aaBBcc. B. AaBBCC * AABbcc. C. AaBbCc * AaBbcc. D. AaBBCc * AaBBCc. E. AABbCc * AABbcc.
