Asexual reproduction

Definition

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

5 Must Know Facts For Your Next Test

1. Asexual reproduction requires only one parent, making it faster and less energy-intensive than sexual reproduction.
2. Common methods include binary fission, budding, fragmentation, and parthenogenesis.
3. Parthenogenesis is a form of asexual reproduction where an embryo develops from an unfertilized egg cell.
4. Many simple organisms like bacteria, archaea, and some plants and animals reproduce asexually.
5. Asexual reproduction does not contribute to genetic diversity; all offspring are clones of the parent.
