An individual variant in a polymorphic population.



the minimal meaningful part of an utterance; a specific representation of a morpheme in a text; one of the variants of a morpheme with nonidentical elements, as in the Russian alternation:

(1) /nos/it’

(2) /nes/ti

(3) /nash/ivat’ [The above three infinitives all contain a morpheme having the basic meaning of “to carry” or “to wear.” Their meaning and usage differs according to their mode of action (in Russian, sposob deistviia; in German, Aktionsart).}

The choice of a morph depends upon its phonological or morphological environment and is subject either to the rules of complementary distribution, as in English plural formants /-s/, /-z/, and /-Iz/, or to the rule of free variation, as in Russian bel/oi/ sten/oi/bel/oiu/ sten/oiu/ (instrumental singular of belaia stena, “white wall“). The morphs of a single morpheme are known as its allomorphs.

They will automatically adjust and/or reconfigure themselves according to their immediate system needs and be able to virtually morph (growing and contracting at will) to meet almost all on-demand needs, all with either pre-designed human involvement (decision making points, particularly when you are just starting your deployment) or eventually without any human intervention at all.
These were Ann Reinking's Fosse (which was an homage to Dancin' and Fosse himself), Lynn Taylor Corbett's Swing, an all-dance revue to pop songs, and finally Susan Stroman's Contact, an experimental evening of three short narrative ballets conceived as a Broadway musical--or, for the morph has morphed, dansical.

Using data from 1,186 antlers collected from moose harvested in southeastern Norway during 1950-1997, I tested the widely held hypothesis that the cervine morph has become the predominant antler type in Norway.
When morph frequencies are relatively constant across populations, it becomes more difficult to differentiate between uniform selection acting over a wide area and the migration of effectively neutral alleles between populations.
Environmental factors influence the determination of the sexual morph, as the AR increases with increasing temperature both under laboratory conditions and in natural populations (Schrag and Read 1992, Schrag et al.
