Is phenotypic plasticity genetic?

Can phenotypic plasticity be inherited?

Previous studies have shown that phenotypic plasticity is a heritable trait which varies among populations and species (Schlicht- ing, 1986). … Conversely, if plasticity had a low heritability we might expect specialized individuals to evolve.

What causes phenotypic plasticity?

Phenotypic plasticity describes the process that allows individuals to alter their phenotype in response to environmental change alter their phenotype due to new environments. … This change in gene expression allows for phenotypic plasticity, as changes in mRNA expression have a direct link to protein abundance.

Is phenotype physical or genetic?

The term “phenotype” refers to the observable physical properties of an organism; these include the organism’s appearance, development, and behavior. An organism’s phenotype is determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences upon these genes.

What is an example of phenotypic plasticity in humans?

From a human health perspective, documented examples of plasticity most commonly include the results of exercise, training, and/or dieting on human morphology and physiology.

Can natural selection act on phenotypic plasticity?

Main Text. Natural selection acts on phenotypes, yet evolution occurs at the level of genotypes. … This suggests that plasticity may largely impede adaptive evolution. However, it has been posited that plasticity may facilitate or even promote adaptation in certain contexts.

Is plasticity under natural selection?

Plasticity can, for example, moderate the effects of natural selection by allowing individuals to adapt phenotypically to new conditions quickly. Chevin et al. [79] have developed a model to predict population persistence in a changing environment.

What are some environmental factors that can influence your phenotype?

Environment Can Impact Phenotype

Environmental factors such as diet, temperature, oxygen levels, humidity, light cycles, and the presence of mutagens can all impact which of an animal’s genes are expressed, which ultimately affects the animal’s phenotype.

What is phenotypic plasticity quizlet?

What is phenotypic plasticity? The ability of a genotype to produce distinct phenotypes when exposed to different environments throughout its ontogeny.
