11) Compare and contrast the processes of mitosis and meiosis. Your answer should not only include a summary of each process, but should discuss both the similarities and differences between them.
Mitosis is an asexual process that results in identical offspring. There is no crossing over or homologous pairs in this process. There is only one division in this process and two diploid cells are formed at the end of it. It results in two daughter cells with the same number of chromosomes. Mitosis has interphase, prophase, metaphase, anaphase, and telophase. In interphase, the chromosomes have already been replicated. In interphase, chromosomes duplicate. During prophase, spindle fibers attach at each centromere. In metaphase, the chromosomes line …show more content…
Unlike mitosis, there is a pairing of homologous pairs and there are two cell divisions that forms 4 haploid cells. There are two parts to meiosis: Meiosis I and Meiosis II. In Prophase I, chromosomes condense and crossing over occurs. During Metaphase I, homologous pairs move the the center of the cell. In Anaphase I, homologous pairs are separated and moved to the poles of the cell. During Telophase I and Cytokinesis, the cell becomes two. In Prophase II, a new spindle fiber attaches to the chromosomes. During Metaphase II, chromosomes line up in the middle of the cell. In Anaphase II, the sister chromatids are pulled apart. During Telophase II and Cytokinesis. the cell divides and four new, genetically different cells are formed. Mitosis and meiosis are both ways to reproduce, however mitosis occurs in somatic cells while meiosis occurs in germ cells to create gametes. Both mitosis and meiosis share similar steps during their processes, although their end results are significantly different. Another similarity between the two is that the cell duplicates the genetic information in both mitosis and meiosis.
