1. MEIOSIS
9 Biology

2. Meiosis Gamete cell division Reduction division:
Only occurs in gametes, or sex cells
Ex. Egg and sperm
Reduction division:
Reduces number of chromosomes by half, resulting in haploid cells

3. Gamete cells:

4. Meiosis Meiosis has 2 phases:
Prophase I, Metaphase I,
Anaphase I, Telophase I, Prophase II, Metaphase II, Anaphase II, Telophase II
Phases are the same as mitosis, but the cells divide twice
Result= half the chromosomes- haploid

6. Meiosis and Mitosis Meiosis Mitosis Only in gamete cells
Results in half the number of chromosomes
Has 2 phases
Results in 4 haploid cells
Happens in somatic (body) cells
Hair, skin, lung, liver
Retains original number of chromosomes
Has 1 phase
Results in 1 daughter cell with chromosome number identical to parent
