In guinea pigs, black fur (B) is dominant over white fur (b). Cross a heterozygous (hybrid) black guinea pig with a homozygous (purebred) white guinea pig. Complete a Punnett square, identify the genotype(s), phenotype(s), and probability (% and fraction) that the offspring will be black and white?
