AP Biology Meiosis Essay

Meiosis is the operation in sexually reproducing organisms where stalls divide. The kiosks produced during meiosis run through i-half the chromosome number as the original prison cellular telephone. thither are two cell divisions in meiosis, meiosis l and meiosis ll. These cell divisions produce 4 hapolid daughter cells. Haploid cells contain only matchless set of chromosomes, which is written as n. Meiosis consists of nine phases. In meiosis the interphase l the chromosomes replicate and the centrosome duplicates in i diploid cell. Diploid cells assimilate two sets of chromosomes, they received one from from severally one parent. During prophase l the nuclear envelope fragments and spindle microtubules variant betwixt the centrosomes. Homologous chromosomes pair to affect two baby chromatids. This is called synapsis. Chromatids of homologous pairs counterchange segments when they bell ringer over. At metaphase l, the pairs line up on the metaphase household. Microtubules from one perch marry to the kinetochore of one homologous chromosome, slice microtubules from the separate pole attach to the kinetochore of the other pair. During anaphase l the microtubules bum shorter move the homologous pairs towards opposite poles. At telophase l two haploidic cells form simply the chromosomes are still double. Meiosis ll separates the babe chromatids. During prophase ll the sister chromatids in each cell begin moving towards the equator. At metaphase ll the chromosomes align on the metaphase plate in each cell. The member of anaphase ll pulls the sister chromosomes to opposite poles in each cell.

During telophase ll each cell forms a nuclei and cytokinesis splits the cells apart. Four genetically different haploid cells are produced. Independent assortment is differences amidst the genes. genetic mutation can occur in meiosis when the chromosomes overcome over and during stochastic dressing. Random fertilization is when a gamete from the mother unites with the haploid from the yield to produce... It was quite informative, but you should fixing the layout of your text because it is annoying to empathise it when the distances between the sentences is big. You should also wipe out a conclusion and introduction. other it was ok If you want to get a full essay, order it on our website: Ordercustompaper.com
