Explanation: Meiosis (not to be confused with mitosis) occurs in every sexually reproducing eukaryote and is required to produce egg and sperm cells. The result of meiosis is four daughter cells.

What Is Genetic Diversity and Why Does it Matter?

WebMeiosis transforms a diploid cell into four haploid granddaughter cells, each having a single copy of each chromosome. The process helps increase the genetic diversity of a species. … WebEach resulting cell, or gamete, resulting from meiosis has only half the amount of DNA as the parent cell.

Fertilization creates genetic diversity by allowing each parent to randomly contribute a unique set of genes to a zygote. While fertilization is not part of meiosis, it depends on meiosis creating haploid gametes. WebJul 22, 2024 · Assess how meiosis contributes to genetic variation while mitosis does not.

WebGenes that are far apart on the same chromosome also assort independently thanks to the crossing over, or exchange of homologous chromosome bits, that occurs early in meiosis I. [See a picture] There are, however, gene pairs that do not assort independently. WebJul 5, 2024 · When changes occur in a cell that produces gametes, future generations are affected. Crossing-over When homologous chromosomes come together during prophase I of meiosis, they exchange bits of DNA with each other.
