In humans the gene for brown eyes (b) is dominant to the gene for blue eyes and the gene for right handedness (r) is dominant to the gene for left handedness. two individuals heterozygous for both of these characteristics marry. a) complete a punnett square to show the expected genotypes and phenotypes of the offspring. b) summarize the ratio of the phenotypes.

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.
