Question

You perform a test cross on some hamsters. You want to know if your brown hamster carries the allele for albinism, a recessive mutation which causes no pigment production. Normal hamsters are BB, and recessive hamsters (bb) have albinism. (Bb) hamsters simply carry the allele, but are still brown. When you breed your hamster (B?) with an albino hamster (bb), you get the following results: 4 brown hamsters and 4 albino hamsters. Does your hamster carry the albino allele? Yes or no?

Answer 1

Answer:

Yes the hamster does carry the albino allele.

Explanation:

A Bb hamster and a bb hamster get a half and half color pattern chance as seen by the 8 babies being evenly divided into two color groups of 4.
