WebAnswer (1 of 5): Meiosis occurs in a diploid sex cell and results in four cells (gametes). All these four haploid/cell gametes are genetically different from each other. The characters … WebWhat is Genetic Diversity? genetic variation, the variety of alleles within a population of a species. Benefit of high genetic diversity? species able to adapt with changes in the environment e. if a new disease arises, some individuals will have characteristics to survive, and will reproduce passing on their alleles, so the species does not ...

WebThe variation introduced into the reproductive cells by meiosis appears to be one of the advantages of sexual reproduction that has made it so successful. Meiosis and fertilization alternate in sexual life cycles. The process of meiosis produces unique reproductive cells called gametes, which have half the number of chromosomes as the parent cell. WebJan 1, 2009 · An alternative view is that the initial benefit of meiosis was enhanced repair of DNA damage via recombination (Bernstein 1977; Bernstein et al. 1988).

WebThe only method that will allow a co-evolving species to maintain its own share of the resources is to also continually improve its fitness. As one species gains an advantage, this increases selection on the other species; they must also develop an advantage or they will be outcompeted. WebThe gametes produced in meiosis aren’t genetically identical to the starting cell, and they also aren’t identical to one another. As an example, consider the meiosis II diagram below, which shows the end products of meiosis for a simple cell with a diploid number of 2n = 4 chromosomes. The four gametes produced at the end of meiosis II are all slightly … WebIn meiosis, each new cell contains a unique set of genetic information. After meiosis, the sperm and egg cells can join to create a new organism. Meiosis is why we have genetic diversity in all sexually reproducing organisms. During meiosis, a small portion of each chromosome breaks off and reattaches to another chromosome. dick powell sings
