- Contain genetic information in the form of Genes
- Requires 2 organisms of the same species
- Fertilisation
- Fusion of Gametes in Animals
- Produces a cell which contains genetic information from both parents
- Cell divides rapidly to produce more cells with each having exactly the same genetic information
- Produces a cell which contains genetic information from both parents
- Fusion of Gametes in Plants
- Produces a cell which contains genetic information from both parents
- This cell is inside a seed which helps it to divide to form an embryo, all the cells of which have the same genetic information.
