Question

Suppose you have a black male rabbit and a black female rabbit. Each has a dominant gene (F) for black fur, but the female also has a recessive gene (f) for white fur. Using a Punnett square, determine the chances for white offspring when these two rabbits mate.

Answer 1

Answer: The chance of these two rabbits having white offspring is 0%

Explanation: When making the Punnett Square, only one square of possible offspring ends up having a (f) recessive allele. This means that even though the offspring has a recessive (f), it’s not enough for the trait to show because of the dominant (F) it’s paired with. Therefore, none of the offspring will be able to be white.
