Based on the above data, answer the follow questions.

State which fur color is dominant (1 pt each).
State which fur color is recessive (1 pt each).
What is the genotype for the black fur (1 pt )
What is the genotypes for the brown fur (2 pts )

Dominant: Brown colored fur

Recessive: Black colored fur

Black Fur Genotype: bb

Brown Fur Genotype: BB, Bb, or bB

Explanation:

B = Brown

b = Black
