Answer:
In guinea pigs, the gene for black fur, B, is dominant over the gene for white fur, b. Complete the Punnett square below to show the results of one possible cross between two guinea pigs with black fur.
BB X Bb = BB, Bb, BB, Bb
Step-by-step explanation:
From the analogy shown, it is obvious that both parents are gene with black fur. During such crossing, the offspring are two homozygous dominant black fur and two heterozygous dominant black fur
