Suppose that in a mammalian species, the allele for black hair (B) is dominant to the allele for brown hair (b), and the allele for curly hair (C) is dominant to the allele for straight hair (c). When an organism of unknown genotype is crossed against one with straight, brown hair, the phenotypic ratio is as follows: 25% curly black hair 25% straight black hair 25% curly brown hair 25% straight brown hair What is the genotype of the unknown parent? A. BbCC B. bbCc C. Bbcc D. BbCc
