In guinea pigs, black hair is dominant to white hair. Heterozygous male guinea pigs with black hair (Bb) are crossed with heterozygous female guinea pigs with black hair (Bb). The incomplete punnett square in Figure 11–4 shows the expected results from the cross. Identify the genotype of the off spring that would be represented by the ?? in Figure 11–4.
