In Labrador Retrievers, coat color is controlled by an epistatic gene. Examine the image below to determine which gene is epistatic and controls the phenotypic expression of the other.

A. Gene "B" is the epistatic gene.
B. The genotype "bb" is epistatic.

C. Gene "E" (EE, Ee, or ee) is the epistatic gene.

D. It cannot be determined from this image.

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.
