Answer:
D. Crossing over
Explanation:
During prophase-I of meiosis-I, a process of genetic recombination occurs. During this process, two non-sister chromatids of the paired homologous chromosomes exchange a part of the genetic segment. This is called crossing over. Crossing over results in the production of recombinant chromatids that carry new combinations of alleles that were otherwise not present in the parental chromosomes. Therefore, crossing over generates some extra combinations of alleles.

<span>Glial cells in the white matter help promote communication between the nerve impulses in the gray matter. They differ because in the peripheral nervous system there is more of a fatty substance that acts as a cushion between the impulses, which is a little different than helping the nerve impulses along intentionally. The cushioning may aid in transmission indirectly, but serves as more of a safety zone.</span>
