Meiosis is a special type of cell division necessary for sexual reproduction. In animals, meiosis produces gametes like sperm and egg cells, while in other organisms like fungi it generates spores. This PowerPoint presentation on meiosis provides a good overview on the topic, and should be used as a foundation that triggers discussion and exploration with your audience.
Topics that the presentation covers are:
Why do we need meiosis?
- Meiosis is necessary to halve the number of chromosomes going into the sex cells
- Why halve the chromosomes in gametes?
At fertilisation the male and female sex cells will provide ½ of the chromosomes each – so the offspring has genes from both parents
Also:
- how cells divide in meiosis
- division error
- meiosis error – fertilisation
- 21 trisomy – Downs Syndrome
