1. Meiosis
The process of cell division in which male and female gametes are produced in order for sexual reproduction to take place

2. Fertilization -The union of two sex cells.
-Sex Cells (reproductive cells) are HAPLOID.
-HAPLOID cells contain only one set of chromosomes ( n)
Only one copy of each gene.
Male Gametes: Spermatozoa (testicles)
Female Gametes: Eggs or Ova (Ovaries)

3. Parent cell divides twice
- produces 4 daughter cells
containing ½ the DNA
of parent cell (n)
- Join to make baby
(2n: complete set of DNA)

4. Meiosis
Diploid 2n
Haploid n

5. Differences between Mitosis and Meiosis
Parent cell diploid
After interphase the Cell divides once:
Prophase
Metaphase
Anaphase
Telophase
Two daughter cells
same genetic material as parents)
Parent cell diploid
But divides twice!
Meiois I
- same as mitosis
- chromosome
pairs separated (half)
- end: each cell 23 chromosomes
Meiosis II
- chromosomes split into 2
- 4 haploid daughter cells
