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.
100%
C.
75%
D.
25%
The possible genotypes for the offspring of an albino rabbit (bb) breeding with a brown rabbit (Bb) are Bb and bb. Since the gene for albinism is recessive, the only way for an albino rabbit to be produced is if both parents contribute the recessive allele (b).
In this case, there is a 50% chance that the brown rabbit will contribute the dominant allele (B) and a 50% chance that it will contribute the recessive allele (b), resulting in a 50% chance of the offspring being albino (bb).
Therefore, the answer is:
A. 50%
