Genotype and Phenotype in Mice: Understanding Genetic Traits

What is the phenotype of the mouse with genotype BBee?

a) Black fur and red eyes
b) White fur and black eyes
c) Black fur and black eyes
d) White fur and red eyes

Answer:

The mouse with the genotype BBee has a phenotype of Black Fur and Red Eyes since the black fur gene is dominant, and the 'ee' genotype results in red eyes.

Explanation:

The phenotype of a mouse with the genotype BBee would be Black Fur and Red Eyes. The capital 'B' indicates the dominant gene for black fur. The 'bb' represents the presence of a recessive gene, which isn't expressed due to the dominant gene. However, the 'ee' genotype suggests that the mouse has two alleles for the 'e' gene, which causes red eyes. Hence, instead of having black eyes, the mouse has red eyes.
