Quick answer
What does “gynogenesis” mean?
A form of reproduction in which the embryo develops from a female gamete without the genetic contribution of male gamete fertilization, although the egg's development may be stimulated by the presence of sperm.

Meaning and Definition
A form of reproduction in which the embryo develops from a female gamete without the genetic contribution of male gamete fertilization, although the egg's development may be stimulated by the presence of sperm.
A specific type of parthenogenesis where the egg is activated by sperm but incorporates no paternal chromosomes. In biology, it can also refer more broadly to female-driven asexual reproduction processes.

FAQ
Frequently Asked Questions
It is a specific type of 'virgin birth' (parthenogenesis), but distinct because it often involves sperm from a male to activate the egg, even though that sperm contributes no genetic material.
No, gynogenesis does not occur naturally in humans. It is observed in some fish, salamanders, and invertebrates.
It allows for rapid population growth as all individuals can produce offspring, and it preserves well-adapted maternal genomes. However, it reduces genetic diversity.
In aquaculture, it is sometimes induced to produce all-female populations of certain fish species, which may grow larger or faster, improving yield.
A form of reproduction in which the embryo develops from a female gamete without the genetic contribution of male gamete fertilization, although the egg's development may be stimulated by the presence of sperm.
Gynogenesis is usually technical/scientific in register.
Gynogenesis: in British English it is pronounced /ˌɡaɪ.nəʊˈdʒen.ə.sɪs/, and in American English it is pronounced /ˌɡaɪ.noʊˈdʒen.ə.sɪs/. Tap the audio buttons above to hear it.

Learning
Memory Aids
Mnemonic
