Sexual Reproduction
The process of reproduction where the nuclei of two gametes (sex cells) fuse to form a zygote (a process known as fertilisation), producing offspring that are genetically different to one another. There are four key features of sexual reproduction:
Male and female gametes fuse
- Sperm and egg cells are the gametes in animals.
- Pollen and ovum cells contain the gametes in flowering plants.
Two parents
Offspring are non-identical
Cells divide by meiosis
