Question

Responses

fur with yellow hairs

fur with black hairs
fur with black hairs

fur with brown hairs
fur with brown hairs

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

Answer 1

The phenotype of a mouse with the genotype Bb, where B is the dominant gene for black fur and b is the recessive gene for brown fur, will be fur with black hairs. In Mendelian inheritance, dominant traits express themselves over recessive traits when present. Therefore, the correct response is:

fur with black hairs.
