Gametes and fertilisation.
Humans reproduce through sexual reproduction and produce offspring that are genetically unique because half of their genetic material -
DNA - comes from each parent.
Gametes are the male and female sex cells:
Ova are female gametes.
Sperm are male gametes.
In sexual reproduction, a male and female gamete can join together. This is fertilisation.
These gametes, the male and female sex cells, are not just ordinary cells. They are specialised, intricately designed cells with unique adaptations. These adaptations significantly increase the chances of successful fertilisation and the subsequent development of a healthy baby.
