Today we used half of the period to introduce our new topic of meiosis. Meiosis is a type of cell division that is specific to sexual reproduction, essentially the production of gametes. Remember gametes are the sex cells produced by individuals (sperm for males and egg cells, (ovum for females) that produce an embryo when combined in fertilization.
In order to fully understand and appreciate Meiosis, it is important to have a basic background in another type of cell division known as Mitosis.
Some questions to consider:
- What types of cells are used in Mitosis? What types for Meiosis?
- What type of cell does Mitosis start with? What type of cell does Mitosis produce?
- What type of cell does Meiosis start with? What type of cell does Meiosis produce?
- How many chromosomes do humans have in a cell (not gametes)?
- How much genetic information is contributed by each parent? How many chromosomes is this in humans?
