WitrynaJada Williams Title: Cell division: Meiosis Intro/ Objective: Meiosis is the second most important process relating to cell division similar to mitosis, but the results of the divisions are different between the two. Mitosis is a constantly ongoing process, repairing, growing, and creating new cells within our bodies, this can be performed in … WitrynaSignificance of meiosis. Meiosis is the nuclear division of diploid cells into haploid cells, which is a necessary step in sexual reproduction; it is a significant chance to introduce genetic diversity into gametes. Sexual reproduction is the production of haploid cells (gametes) and the fusion (fertilization) of two gametes to form a single ...
