Definition of allogamy in English:

allogamy

noun əˈlɒɡəmiəˈlɑɡəmi

mass nounBotany

The fertilization of a flower by pollen from another flower, especially one on a different plant.
〔植〕异花受粉（尤指异体受精）。比较AUTOGAMY
Compare with autogamy
Example sentencesExamples
- Changes in floral morphology are normally required to promote either autogamy or allogamy.
- Simulations were based on a Wright-Fisher model, with two modifications: separate sexes (with an equal sex ratio) and strict allogamy (no selfing).
- The allogamy in the genus Helianthus is favoured by the particular mechanism of anthesis in which anthers shed pollen before the stigma of the same flower is ready to receive it.
- Similar patterns were observed for 100% allogamy and 10% allogamy.
- This specialized system is thought to be an adaptation promoting allogamy by secondary pollen presentation.

Derivatives

allogamous

adjective

Botany

The construction of maps of autotetraploids is a much greater problem than that of maps of allogamous diploids.
Example sentencesExamples
- In the literature, few studies of gene nucleotide diversity have considered both within-population and between-population variation in allogamous plants.
- A double pseudo-testcross strategy has generally been adopted for constructing genetic maps in conifers having allogamous characteristics.
- Some species are self-compatible (thereafter called SC species) and are obligatorily or facultatively autogamous, while other species have a self-incompatible locus (SI species) and are obligatorily allogamous.
- On the other hand, invading species with predominantly allogamous modes of reproduction may possess a high level of genetic diversity.

Origin

Late 19th century: from allo- 'other, different' + Greek -gamia (from gamos 'marriage').
