Quick Meiosis (and Mitosis) Review

Compared to mitosis, meiosis results in-

• greater number of chromosomes per cell

• greater volume of cell cytoplasm per cell

• greater number of daughter cells

• greater amount of genetic material per cell

Meiosis plays a more significant role in reproduction than mitosis in that-

• it increases genetic variability

• it uses energy more efficiently

• it reproduces more rapidly

• its important in asexual reproduction
