Question

for this question, assume brown fur (b) is dominant to white fur (b) in mice and that fur color is controlled by a single gene. select all of the following mice that would have brown fur. a. bb b. bb c. bb

Explanation:

In genetics, when a trait is controlled by a single gene and one allele (here \(B\)) is dominant over another (\(b\)), an organism will show the dominant trait if it has at least one copy of the dominant allele. For option A (\(bb\)), since there is no dominant \(B\) allele, the fur color is white. For option B (\(Bb\)), there is a dominant \(B\) allele, so the fur color is brown. For option C (\(BB\)), there are two dominant \(B\) alleles, so the fur color is brown.

Answer:

B. \(Bb\), C. \(BB\)
