The Answer of In rats, the P gene allele for pigmentation (P) is dominant to the allele for albinism (p). The B gene allele for black pigmentation (B) is dominant to the allele for cream pigmentation (b). The pp homozygous recessive genotype is epistatic to any allele combination at gene B. -Predict the genotypes and phenotypes of the F₁ progeny of a cross between a pure-breeding black rat and an albino that is also homozygous for cream. A)PP BB, black B)Pp Bb, black C)Pp Bb, albino D)pp Bb, albino
