2. Question
If humans have a diploid number of 46 chromosomes, what is the haploid number of chromosomes? Answer: 23

3. Meiosis
Meiosis- a type of cell division that produces four cells, each with half the number of chromosomes as the parent cell.

4. Meiosis In animals, meiosis occurs in the sex organs
The testes in males
The ovaries in females
A gamete, or sex cell, is a haploid cell
Meaning this cell contains only one of each kind of chromosome
A diploid cell found in body cells
Which have two of each kind of chromosome.

5. Mitosis vs Meiosis
Mitosis results in the production of two genetically identical diploid cells
Meiosis produces four genetically different haploid cells in two stages
1st meiotic division
2nd meiotic division

6. In males, meiosis results in four sperm cells that are the same size.
Spermatogenesis

7. In females, four cells are produced-one large egg and three smaller polar bodies.
Oogenesis
