phenotypic plasticity

phenotypic plasticity

or

environmental variation

the ability of an organism to alter greatly its PHENOTYPE depending upon environmental conditions. The phenomenon is seen most clearly in plants, perhaps because they are fixed in the ground. For example, a dandelion will produce an erect habit with long flower stalks if in a garden border with other plants. Another dandelion with a similar genotype will produce a PROCUMBENT habit with short flower stalks if grown in a garden lawn.

Conover and Schultz (1995) used reciprocal transplant experiments with the Atlantic silverside (Menidia menidia) to test whether countergradient variation in growth and size (faster growth and larger individuals in cooler northern regions) was due to phenotypic plasticity in response to variable environmental conditions.
(10) Sex change in teleost fish offers a dramatic example of environmentally cued phenotypic plasticity unprecedented in any other group of vertebrates.
While genetic differences are also bound to influence the evolution of phenotypic plasticity, ecophenotypic variation in gastropod shells in response to multiple predators may explain geographic and temporal variation in shell morphology (Appleton and Palmer, 1988; Palmer, 1990).
However, There is a paucity of information on how the human immune system co-adapts to the parasites phenotypic plasticity, And how it dynamically rearranges its molecular phenotypes aiming to counteract the pathogenic threats.

The degree to which these phenotypic responses represent adaptive evolution or phenotypic plasticity remains an active area of investigation, with evidence for both evolution and plasticity found in several studies (reviewed in [21]).
However, understanding the complete impact of climate change-induced coat colour mismatch on hare demography requires a detailed understanding of the potential for phenotypic plasticity or microevolution in the phenology of coat colour moults in the species.
Goal of this research was to recognize variations in chromosomal stoichiometry especially of complete ploidal change between specimens, within specimens and between cells within specimens of the species Girardia schubarti (Marcus, 1946), any tendencies those variations might present and any relations they might have with selected components of phenotypic plasticity (PP).

Phenotypic plasticity has been defined as the ability of a single genotype to produce more than one alternative morphological form in response to environmental conditions (1).
Adaptive phenotypic plasticity (the ability of a single genotype to change its phenotype in res ponse to environment cues) is often key to optimizing crypsis in animals whose habitat is heterogeneous through space or time (Umbers et al.
