Which of the following tasks is accomplished through the process of meiosis?


You need to recognize the distinctions and similarities in the procedures of mitosis and also meiosis and relate theseto theprocesses of sex-related and also asexual reproduction. You must understand how mitosis and meiosis lead to genetic variation. You have to understand the relationship between mutation, cell cycle, and also unregulated cell development possibly bring about cancer. You must understand the cell cycle, consisting of the procedure of mitosis and also be able to describe the role of mitosis in the formation of brand-new cells and its importance in maintaining chromosome number in the time of sex-related remanufacturing.
