Fur color in mice is affected by a gene with two alleles. The B allele causes dark brown fur and is completely dominant over the b allele that causes light brown fur. What is the fur color of a mouse with the genotype Bb?Multiple choice question.Light brown furVery dark brown fur due to two different alleles being presentDark brown furA mixture of dark brown and light brown fur
