Asexual reproduction

Definition

Asexual reproduction is a mode of reproduction where offspring are produced by a single parent without the involvement of gamete fusion. This process results in offspring that are genetically identical to the parent.

5 Must Know Facts For Your Next Test

1. Asexual reproduction includes processes such as binary fission, budding, and fragmentation.
2. In parthenogenesis, an egg develops into an organism without fertilization.
3. Hydras reproduce asexually through budding, where a new individual grows out of the parent's body.
4. Starfish can reproduce through fragmentation, where parts of their bodies regenerate into new individuals.
5. Asexual reproduction allows for rapid population growth in stable environments but decreases genetic diversity.
