Sexual reproduction requires two key cellular processes:
- Meiosis — a reduction division that produces haploid gametes (sperm and egg in animals) from diploid germ cells. Meiosis also produces genetic variation via crossing-over and independent assortment.
- Fertilization (syngamy) — fusion of two haploid gametes to restore the diploid chromosome number and form a zygote.
Together these processes reduce and then restore chromosome number and generate genetic diversity.
