What is the phenotype of a mouse that has the genotype Bb where capital B is the gene for black fur and b is the gene for brown fur, assuming the gene follows a Mendelian inheritance pattern?(1 point)

Question

Responses

fur with brown hairs
fur with brown hairs

fur with black hairs
fur with black hairs

fur with both black and brown hairs
fur with both black and brown hairs

fur with yellow hairs

Answer 1

The phenotype of a mouse with the genotype Bb, where B is the gene for black fur and b is the gene for brown fur, would be fur with black hairs. In Mendelian inheritance, the dominant allele (B) will determine the phenotype, so the presence of at least one dominant allele results in the expression of the dominant trait (black fur).
