Fur color is a trait controlled by a dominant over recessive gene. The fur color is either brown or black. Two brown mice and produce 12 offspring. Three (25%) of the offspring produced are black fur and nine (75%) have brown fur.

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

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
