Definition of ontogenesis in English:
ontogenesis
noun ˌɒntə(ʊ)ˈdʒɛnɪsɪsˌɑn(t)oʊˈdʒɛnəsəs
mass nounBiology The development of an individual organism or anatomical or behavioural feature from the earliest stage to maturity.
Compare with phylogenesis
Example sentencesExamples
- Since this field of biogenesis is not available to us, we shall do as biologists do and turn to ontogenesis.
- Some degree of variation seems attributable to ontogenesis, as large morphological distances are observed between young and adult specimens.
- Ductal plate malformation results from persistence or absence of remodeling of the embryonic ductal plate during ontogenesis.
- The concepts of penetrance and expressivity and also of the systemic regulation of the formation of phenotypic traits - the foundation of phenogenetics and the genetics of ontogenesis.
- Shepard proposes that humans go through eight stages of ontogenesis in their first twenty years of life.

adjective ˌɒntə(ʊ)dʒɪˈnɛtɪk
Biology Extant birds are the most appropriate models for understanding the ontogenetic and phylogenetic development of PSP in sauropods.
Example sentencesExamples
- Thus, there is no mechanism of ontogenetic developmental concrescence, just differentiation.
- This phenomenon owes its existence to both phylogenetic and ontogenetic naturalistic processes.
- During its ontogenetic growth, an organism would experience various developmental events.
- The activational effects of sex-limited steroids buffer male and female phenotypes from ontogenetic conflict.
adverb ˌɒntə(ʊ)dʒɪˈnɛtɪk(ə)li
Biology This is obvious but important, because if camerae can be derived from fossae ontogenetically then they can also be derived from fossae phylogenetically.
Example sentencesExamples
- In some species, males facultatively or ontogenetically switch between these tactics, and in other species the tactics appear to be fixed for an individual's lifetime.
- Thus, the resultant planktonic cephalopods are probably trapped, either evolutionarily or ontogenetically.
- Combined with their occasionally distinctive morphologies, it would appear that they represent structures ontogenetically and functionally distinct from the botuliform cells.
- In the other clade characterized by a static level of disparity, Clade 5 the structure changes ontogenetically, although more subtly than in Clade 4.
Origin
Late 19th century: from Greek ōn, ont- 'being' + genesis 'birth'.
