Albino rabbits are rabbits that don't have any pigmentation in their fur or eyes. Their eyes appear pink and their fur appears pure white. The gene for albinism is a recessive gene. If an albino rabbit (bb) breeds with a brown rabbit (Bb), what is the percent chance that they will produce an albino rabbit?

A.
50%

B.
75%

C.
100%

D.
25%

The chance of producing an albino rabbit can be determined by understanding the possible combinations of genes that can be passed on from the parents.

In this case, the albino rabbit is homozygous recessive (bb) for the albinism gene, while the brown rabbit is heterozygous (Bb).

When the two rabbits breed, they can pass on either the gene for albinism (b) or the gene for brown fur (B) to their offspring.

There are four possible combinations:

1. Bb: This offspring will have brown fur, but will carry the gene for albinism.
2. Bb: This offspring will have brown fur, but will carry the gene for albinism.
3. bb: This offspring will be albino, as it will receive the albino gene from both parents.
4. bb: This offspring will be albino, as it will receive the albino gene from both parents.

Out of the four possible outcomes, two of them (3 and 4) result in albino offspring.

Therefore, the percent chance of producing an albino rabbit is 2/4 or 50%.

The correct answer is A. 50%.
