agamogenesis
Very LowTechnical/Scientific
Definition
Meaning
Reproduction without fertilisation; asexual reproduction.
In biology, a mode of reproduction where offspring arise from a single organism, inheriting genes solely from that parent, without the fusion of gametes. It includes processes like binary fission, budding, fragmentation, and parthenogenesis, and is common in many plants, invertebrates, and some reptiles.
Linguistics
Semantic Notes
The term is primarily used in specialized biological, zoological, or botanical texts. It encompasses various asexual reproductive strategies. It is not synonymous with "cloning" in a modern genetic sense, though it can be a form of natural cloning.

Examples
By CEFR Level
- Some simple organisms can reproduce through agamogenesis, creating identical copies of themselves.
- The textbook explained that agamogenesis is common in many plant species.
- The researchers observed a facultative shift to agamogenesis in the Daphnia population when males were absent.
- A key advantage of agamogenesis is the rapid population growth it enables in stable environments.
Learning
Memory Aids
Mnemonic
Think 'A-gamete-genesis': genesis (creation) WITHOUT (the 'a-' prefix) the fusion of GAMETES (sex cells).
Conceptual Metaphor
REPRODUCTION IS CLONING (in this specific context).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- The Russian term 'агамогенез' is a direct cognate with identical meaning. No false friends exist.
Common Mistakes
- Misspelling as 'agamogenisis' or 'agamognesis'.
- Confusing it specifically with 'parthenogenesis', which is a type of agamogenesis.
- Using it as a general synonym for 'reproduction' without the asexual specification.

Frequently Asked Questions
While both produce genetically identical offspring, 'cloning' is a broader modern term that includes laboratory techniques. Agamogenesis refers specifically to natural, asexual reproductive processes in organisms.
Yes, it occurs in many invertebrates (e.g., rotifers, aphids, some lizards) and a few vertebrates, like some species of fish and reptiles, through processes like parthenogenesis.
It limits genetic diversity, making populations more vulnerable to diseases and environmental changes because all offspring are genetically identical to the parent.
In British English: /ˌæɡəmə(ʊ)ˈdʒɛnɪsɪs/ (ag-uh-moh-JEN-uh-sis). In American English: /ˌæɡəmoʊˈdʒɛnəsəs/ (ag-uh-moh-JEN-uh-suhs). The stress is on the 'gen' syllable.
