Mitosis
the division of a cell that results in 2 identical cells. Same genetic information, same number of chromosomes as the starting cell. Body cells do this
Meiosis
the division of a cell that results in 4cells. each with half the number of chromosomes of the starting cell, genetic information is mixed up. used to make reproductive cells (sperm and egg)
46 Chromosomes
Number of chromosomes In a normal HUMAN body cell
23 Chromosomes
Number of chromosomes in a HUMAN reproductive cell (sperm and egg)
1 Time
