B2 - Cell Division: Meiosis

  • Cellular reproduction
  • Half the number of chromosomes
  • Double split
?
Where does meosis occur?
In the reproductive organs (cells with only half the genetic information).
1 of 5
What is meosis?
Meosis produces cells which have half the normal number of chromosomes (gametes).
2 of 5
How does meosis happen?
The cell duplicates it's DNA. In the first division, the chromosome pairs line up and the cell is pulled apart so each has only one set of the chromosomes. In the second division, the cell fibres pull the cell apart so split the chromosomes.
3 of 5
How many gametes are produced by this process?
Four gametes are made by one cell.
4 of 5
Where would this happen in a human?
Only in the reproductive organs (ovaries and testes).
