1. Meiosis (Gamete formation)

2. Reproduction of Sex Cells
Sex cells (gametes)- Sperm and egg
Process is called Meiosis
Similar to Mitosis

3. Meiosis Cell divides twice
First division is like mitosis and then the cell divides again to create 4 haploid cells.

4. MEIOSIS=CHROMOSOME REDUCTION DIVISION

5. Meiosis Meiosis is also know as chromosome reduction division.
Start with 46 and ends up with 23.
Why?
Fertilization creates the diploid condition again
Haploid
Diploid

6. Sperm formation- 4 haploid sperm cells are formed.
Egg formation-most of the cytoplasm is used in one cell and the other three disintegrate. One haploid egg cell is formed.

8. Comparison of mitosis and meiosis

9. Crossing Over
Sometime during meiosis the chromosomes can exchange information
This is called Crossing Over
Major source of genetic diversity in the species

11. Prokaryotic Cells Binary fission Occurs in Prokaryotic Cells
DNA is copied and then the cell splits in half.
