A mode of reproduction in which the offspring comes from a single organism, and not from the union of gametes as it is in sexual reproduction
Asexual reproduction is a type of reproduction wherein the offspring comes not from the union of gametes but from other means. There are different means of asexual reproduction:
- Binary fission
- Vegetative propagation
- Spore formation (sporogenesis)
- Nucellar embryony
Asexual reproduction is the mode of reproduction in prokaryotes. In particular, prokaryotes reproduce through binary fission. Eukaryotes, especially higher forms of animals, reproduce through sexual means, i.e. by sexual reproduction. In sexual reproduction, gametes are produced by meiosis. A male gamete fertilizes the female gamete, forming a zygote. Some eukaryotes are capable of asexual reproduction. In asexual reproduction, the organism is capable of reproducing an offspring in the absence of a mate. As a result, the offspring is a clone of the parent and therefore results in low genetic variation in the species as a whole. Some species are capable of heterogamy, i.e. the ability to alternate between sexual and asexual reproduction.
