Gametes do not have the same genetic composition formed by the parent organism.
Gametogenesis:
Gametogenesis:
- When male and female gametes are similar in appearance and it is not possible to differentiate between them, they are called homogametes or isogametes.
- When the male and female gametes are morphologically distinct, they are called heterogametes.
- Among heterogametes, the male reproductive unit is called antherozoid or sperm and female reproductive unit is called egg or ovum.

- Unisexual female flowers bearing pistils are called pistillate flowers.
