1. Meiosis: This is a type of cell division that produces gametes (sex cells) with half the number of chromosomes as the parent cell. This ensures that when two gametes combine during fertilization, the offspring receives the correct number of chromosomes.
2. Fertilization: This is the process where two gametes (one from each parent) fuse together to form a zygote. The zygote then develops into an embryo, which eventually grows into a new organism.
