In a certain mouse population, gene B codes for black fur, and b codes for brown fur. This gene follows the Mendelian inheritance pattern - the trait is only determined by one gene. What is the phenotype of a mouse that has the genotype Bb? (1 point)

Question

Answer 1

The phenotype of a mouse that has the genotype Bb would be "fur with black hairs." In Mendelian inheritance, the dominant allele (B) masks the presence of the recessive allele (b), resulting in the dominant trait being expressed.
