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?
To determine the percent chance of producing an albino rabbit, we need to consider the genotype of the brown rabbit (Bb).
Since the gene for albinism is recessive (b), the albino rabbit has a genotype of bb.
The brown rabbit (Bb) has one dominant allele (B) for pigmentation and one recessive allele (b) for albinism.
When these two rabbits breed, the possible genotypes of their offspring are:
- BB (brown)
- Bb (brown)
- Bb (brown)
- bb (albino)
Out of the four possible genotypes, only one includes the recessive allele (bb) for albinism.
Therefore, the chance of producing an albino rabbit is 1 out of 4, or 25%.
