The correct anser is option (A) During an especially cold winter, brown squirrels that had thick coats survived at higher rates than brown squirrels whose coats were not as thick.
Natural selection is a mechanism of evolution proposed by Charles Darwin. It is the differential survival and reproduction of individual due to the difference in the phenotype. Over time, this process results in populations which are better adapted to their environment as they tend to survive and produce new offspring. The brown squirrels with thick coat survive at a higher rate than the brown sqirrels without the thick coat. Thick coat is a adaptation for survival in cold winters which are chosen over the other and allowed to reproduce.

Sex of rabbit = Male (bc males produce sperm cells)
The offspring is not genetically identical to either parent because in sexual reproduction, the offspring receives one full set of genes from each parent, making the offspring look similar to the parent but not identical to them.
