How does Meiosis differ from Mitosis Students will know they are successful when they can……….. 1.Explain the reduction of chromosome number that occurs.
Chapter 10: Cell Division Before a cell divides, its Chromosomes replicate and the nucleus divides.
Meiosis. Meiosis is a form of cell division where diploid body cells make haploid gametes. In humans, this means cells that have 46 chromosomes (2N) divide.
