The following genotypes of two independently assorting autosomal genes determine coat color in rats:
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. Determine the F 1 phenotypic ratio of the following crosses: (a) AAbbCC × aaBBcc ; (b) AaBBcc × AABbcc ; (c) AaBbCc × AaBbcc.
