Genotype and Phenotype of Mice

What is the phenotype of a mouse with the genotype BBee in terms of fur color and eye color?

A. Black fur and black eyes
B. White fur and red eyes
C. Black fur and red eyes
D. White fur and black eyes

Answer:

A mouse with the genotype BBee will have Black fur and Red eyes.

Genotypes are written like BBee where the letters represent genes, and they're expressed through observable traits known as phenotypes.

The phenotype of a mouse with the genotype BBee will relate to the characteristics of fur color and eye color the mouse would visibly show. In this case, 'BB' denotes Black fur and 'ee' denotes Red eyes. Therefore, a mouse with this genotype would have Black fur and Red eyes. It's important to know that genotypes are expressed in phenotypes which are observable traits. The genotype determines these traits. For example, in terms of mice fur and eye color, a B stands for the dominant black fur gene, while a b stands for a recessive non-black fur gene. Similarly for eyes, E stands for dominant non-red eye gene while e stands for recessive red eye gene.
