3.2 Fertalisation

3.2 understand that fertilisation involves the fusion of a male and female gamete to produce a zygote that undergoes cell division and develops into an embryo

1. The Adult male and female Gametes are formed by Meiosis
2. These Gametes have half the number of chromosomes as a diploid cell
3. The two opposite gametes fuse to form a zygote, this is now a diploid cell containing a full set of chromosomes
4. The Zygote goes the mitosis to divide into a ball of cells, known as a blastula which then grows to form the embryo.

I have created the diagram below to try to visually explain the concept.
