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.
75%
B.
25%
C.
100%
D.
50%
The percent chance that they will produce an albino rabbit is 50%.
To determine this, we need to use Punnett Square.
The genotype of the albino rabbit is bb, and the genotype of the brown rabbit is Bb.
When we cross these two rabbits, we get the following Punnett Square:
| B | b |
--|---|---|
B | Bb | Bb |
b | Bb | bb |
Out of the four possible outcomes, two of them have the genotype for albino rabbit (bb).
Therefore, the chance of producing an albino rabbit is 2/4 or 50%.
The correct answer is D. 50%.
