WebJan 28, 2024 · Phenotypic plasticity is the variation in phenotype produced by a single genotype in different environments. Along with adaptive evolution, plasticity is expected to play an important role in species' responses to climate change, because each can alter the range of phenotypes expressed in a population as the environment changes. WebIf phenotypic plasticity can be an adaptation, it must be the product of natural selection; hence, there must be heritable variation in plasticity within a population for plasticity to …

WebFeb 1, 2024 · Phenotypic effects on transposable element polymorphisms There are a number of different mechanisms through which TE insertions could affect phenotypes (reviewed in detail in [ 6]), and understanding the prevalence of these different mechanisms is crucial for determining the role TEs play in shaping phenotypic variation. Plasticity is usually thought to be an evolutionary adaptation to environmental variations that is reasonably predictable and occurs within the lifespan of an individual organism, as it allows individuals to 'fit' their phenotype to different environments. If the optimal phenotype in a given environment changes with environmental conditions, then the ability of individuals to express different traits should be advantageous and thus selected for. Hence, phenotypic plasticity can e…
