What Are the Dominant and Recessive Traits in Mice's Fur and Eye Color?

What are the dominant and recessive traits in mice's fur color and eye color? What is the genotype and phenotype of a mouse with black fur and black eyes?

Dominant and Recessive Traits in Mice's Fur and Eye Color

In this lab, you will study mice with two traits: fur color and eye color. Let's first understand the dominant and recessive traits in mice's fur and eye color.

The dominant trait for fur color is black (represented by the letter "B"), while the recessive trait is white (represented by the letter "b"). Similarly, the dominant trait for eye color is black (represented by the letter "E"), and the recessive trait is red (represented by the letter "e").


Genotype and Phenotype of a Mouse with Black Fur and Black Eyes

The mouse in question has the genotype "bbee" and the phenotype of black fur and black eyes. Let's break down the genotype and phenotype:

Genotype: bbee

Phenotype: Black fur and black eyes

Despite carrying the recessive traits for fur color (white) and eye color (red), the mouse displays the dominant traits of black fur and black eyes due to the dominance of these traits in mice.
