In his experiments, mendel bred together plants with similar traits until he had distinct populations that were unvarying for those traits. offspring of crosses of individuals within a population that always show the same trait are described as:

Homozygous

Explanation:

Homozygous individuals are those who do not have genetical variation, it means that they will always look the same generation after generation, those individuals are vulnerable to not adapt to natural selection due to his lack of genes.

You can see homozygous every day, just looking at some pure breeds of dogs or other animals.

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.
