Meiosis: Our Life Mechanism

MEIOSIS: OUR LIFE MECHANISM Radley Carter Genetics, GB 425 Spring 2011 ABSTRACT. miosis is the jail carrel duplication that eucaryotic organisms undergo for reproduction. This influence of division facilitates knowledgeable reproduction. If eukaryotes reproduced d one(a) mitosis, they would be clones of their family line and ineffectual to reproduce sexually. If they reproduced sexually using myosis, Every future contemporaries would be polyploidy organisms where chromosomes ontogenesis with each generation. Polyploidy conditions atomic number 18 usually fatal to most animals. The stages of reduction division incur with prophase I, which is the set up phase before pupillary reflex real begins. Prophase one is profligate into a G1, S, and G2 phase. The DNA in the cell replicates and the cell grows. The cell whence goes to miosis I, the chromosomes argon split and two monoploid cells are the result. Both haploid cells then go through meiosis II, where the chromatids split and are seen as individual chromosomes. The result is quartet cells with half the chromosomes as the passe-partout cell. In animals, manlys and egg-producing(prenominal)s go through meiosis moderately differently. The male produces spermatogonia that go through mitosis to make more diploid spermatagonia. close to go through meiosis to make four spermatids.

The female goes through the same process, only the cells that go through meiosis have unequal splittings, resulting in only one ovum produced instead of four. Problems in meiosis can run chromosome mutations much(prenominal) as deletions, inversions, translocatio ns, aneuploidy, and polyploidy. Some are let! hal depending on which chromosome is affected or where the mutation occurs on a chromosome. INTRODUCTION. In reproduction, meiosis and mitosis are very similar as furthermost as what happens in each individual phase of both processes. Meiosis, however, is what separates eukaryotic reproduction from prokaryotic reproduction. Whereas mitosis ends up with two cells identical to the original, meiosis ends with four cells with half as many chromosomes as the...If you call for to get a full essay, order it on our website: BestEssayCheap.com
