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 or not 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. Determine the F1 phenotypic ratio of the following crosses:
a. AAbbCC x aaBBcc
b. AaBBcc x AABbcc
c. AaBbCc x AaBbcc.
