Genetic basis of plasticity in plants
Webgenetic variance caused by decanalization in an extreme environment can facilitate adaptation in a sink popula-tion. In our model, evolving plasticity favours the adapted equilibrium because with linear reaction norms, variance in plasticity increases the genetic variance in extreme environments, augmenting the rate of adapta- http://desmaraislab.scripts.mit.edu/lab/home/wp-content/uploads/2024/05/Des-Marais-et-al-AREES-2013.pdf

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.
