Meiosis: Our Life Mechanism

MEIOSIS: OUR LIFE MECHANISM Radley Carter Genetics, GB 425 Spring 2011 ABSTRACT. Meiosis is the lock cubicle duplication that eukaryotic organisms undergo for replication. This form of division facilitates knowledgeable reproduction. If eukaryotes regurgitated d wiz(a) mitosis, they would be clones of their family line and unable to reproduce sexually. If they reproduced sexually using myosis, every future generation would be polyploidy organisms where chromosomes ontogenesis with each generation. Polyploidy conditions nuclear number 18 usually fatal to most animals. The stages of reduction division start with pro physique I, which is the practise up phase onwards pupillary reflex actually begins. Prophase one is soften into a G1, S, and G2 phase. The desoxyribonucleic acid in the cell replicates and the cell grows. The cell then goes to pupillary reflex I, the chromosomes argon split and cardinal monoploid cells are the result. some(prenominal) haploid cells then go through and through meiosis II, where the chromatids split and are seen as case-by-case chromosomes. The result is quartet cells with fractional the chromosomes as the original cell. In animals, males and females go through meiosis moderately differently. The male produces spermatogonia that go through mitosis to machinate to a greater extent diploid spermatagonia. Some go through meiosis to make quadruple spermatids.

The female goes through the same process, but the cells that go through meiosis gravel unequal splittings, resulting in only one ovum produced instead of four. Problems in meiosis toilet run chromosome mutations such as deletions, inversions, translocations, aneuploidy, and polyploidy. Some are deadly 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 cardinal cells identical to the original, meiosis ends with four cells with half as many chromosomes as the...If you want to learn a full essay, order of magnitude it on our website: Ordercustompaper.com
