Given the inheritance pattern of the coat color in rats described in the previous problem, 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
Previous problem information:
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.© BrainMass Inc. brainmass.com October 9, 2019, 7:21 pm ad1c9bdddf
