Offspring that are produced through sexual reproduction are usually similar, but never identical, to their parents. this is because a. half of the offspring's genes come from one parent while the other half comes from the other parent. b. genes mutate during every occurrence of sexual reproduction. c. all of the offspring's genes only come from one parent or the other. d. genes are not transferred between parents and offspring during sexual reproduction.

The correct answer would be option A

Sexual reproduction is a type of reproduction in which two parents of the opposite gender are involved.

It involves formation as well as the fusion of male and female gametes.

Thus, in sexual reproduction, the genetic makeup of the offspring is contributed by both the parents due to which offspring produced are similar but not identical to their parents.

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.
