Explain how a mutation that allows normal levels of infant survival at high altitudes would spread through a human population that had just begun living high in the mountains. WebSpecial Issue Information. The contribution of genetic differentiation and phenotypic plasticity in modulating functional trait variability is key for the capacity of forest trees to thrive in complex environments. However, the relative importance of genetic change and plasticity underlying intraspecific variability remains insufficiently studied.

WebA polyphenic trait is a trait for which multiple, discrete phenotypes can arise from a single genotype as a result of differing environmental conditions. It is therefore a special case of phenotypic plasticity.. There are several types of polyphenism in animals, from having sex determined by the environment to the castes of honey bees and other social insects. WebPhenotypic plasticity refers to the potential for the modification of survival- and reproduction-related phenotypes in response to social and ecological (e.g., food) conditions, but within genetically based constraints (Roff, 1992 ).

Webvelopmental plasticity from "genetic" adaptation (Baker 1966; Lasker 1969). Given the historical difficulties of associating specific genes with phenotypic traits, human biologists have concentrated their attention on human plasticity, with the assumption that plastic traits are not under genetic control. As a result the WebAug 18, 2024 · One long-recognized example is genetic assimilation, as classically illustrated by Waddington's [ 37] fruit fly breeding experiments in which an environmentally induced phenotype was, after multiple generations of exposure, eventually expressed in the absence of the inducing stimulus.

WebMar 14, 2014 · Increasingly, researchers are beginning to argue that environmental heterogeneity and long-term ecological stochasticity have sculpted a remarkable breadth of phenotypic plasticity as the primary means by which humans have succeeded in replicating their genetic material 1,2.

WebPhenotypic plasticity is defined as the property of organisms to produce distinct phenotypes in response to environmental variation. While for more than a century, biologists have proposed this organismal feature to play an important role in evolution and the origin of novelty, the idea has remained contentious.

The average human alive today is taller than the average human alive 100 years ago — but this change is not the result of evolution.
