why does sexual reproduction require both Meiosis and syngamy
Homework Answers
Sexual reproduction is the involvement of two parents. in which the male gametes is fused with female gamates. The gamates are alwaya in haploid form, the diploid organism produces gamates through meiosis results in haploid gamates it contain half the number of chromosomes of parent , the diploid number is restored when haploid gamates fuse with another haploid gamates this fusion is called syngamy or fertilizationn. This helps to keep a constant number of chromosomes in successive generation of species. these results the genetic variation among the offsprings due to the exchange of genetic materials. This variation are important in the process of evolution.

Description Review 8 Meiosis and Sexual Reproduction Use complete sentences. 1. Summarize the role of meiosis in the human life cycle. 2. Compare sister chromatids to homologous chromosomes. 3. Identify two means by which meiosis results in genetically different gametes, and explain why this is important. 4. Compare the results/outcome of mitosis vs. meiosis. 5.

Why must all sexually reproducing organisms have both mitosis and meiosis in their life cycles? In other words, what is the purpose of meiosis AND what is the purpose of mitosis and how are they different? Without sexual reproduction evolution would be extremely slow. Why ? And what stage and steps in meiosis are so important to the genetic variation within a species?
