Question

According to the mendelian inheritance pattern, where the trait is only determined by one gene, mice where gene B codes for black fur and b codes for brown, what is the phenotype for a mouse with the genotype Bb?(1 point)
Responses

both black & brown hairs
both black & brown hairs

fur with black hairs
fur with black hairs

fur with brown hairs
fur with brown hairs

fur with yellow hairs

Answer 1

In Mendelian inheritance, the trait determined by a dominant and recessive gene follows a simple pattern. In this case, the allele B (black fur) is dominant over the allele b (brown fur). Therefore, a mouse with the genotype Bb would have black fur because the presence of at least one dominant allele (B) is enough to express the dominant trait.

So, the correct response is:

**fur with black hairs.**
