Assuming that the gene for fur color follows a simple Mendelian inheritance pattern, where the dominant allele (B) produces black fur and the recessive allele (b) produces brown fur, the phenotype of a mouse with the genotype Bb would be black fur.
In Mendelian inheritance, if an individual has at least one dominant allele (B), it will display the trait associated with that allele (black fur). For the brown fur phenotype to be expressed, an individual must have two copies of the recessive allele (bb). Since the mouse in question has one dominant allele (B) and one recessive allele (b), the dominant black fur phenotype will be observed.
what is the phenotype of a mouse that has the genotype Bb where B is the gene for black fur and b is the gene for brown fur assuming this gene follows a Mendelian inheritance pattern?
