Phenotypic plasticity and experimental evolution

Phenotypic plasticity and experimental evolution.

Natural or artificial selection that favors higher values of a particular trait within a given population should engender an evolutionary response that increases the mean value of the trait. For this prediction to hold, the phenotypic variance of the trait must be caused in part by additive effects of alleles segregating in the population, and also the trait must not be too strongly genetically...

Experimental Evolution of Adaptive Phenotypic Plasticity in a Parasite

Coinfection of parasite genotypes can select for various changes in parasite life history strategies relative to single genotype infections, with consequences for disease dynamics and severity. However, even where coinfection is common, a parasite genotype is also likely to regularly experience single genotype infections over relatively short periods of evolutionary time, due to chance, changes...

Genetic adaptation counters phenotypic plasticity in experimental evolution

Amphibious fishes: evolution and phenotypic plasticity.

Amphibious fishes spend part of their life in terrestrial habitats. The ability to tolerate life on land has evolved independently many times, with more than 200 extant species of amphibious fishes spanning 17 orders now reported. Many adaptations for life out of water have been described in the literature, and adaptive phenotypic plasticity may play an equally important role in promoting favou...

Phenotypic plasticity and evolution by genetic

Introduction Why revisit a 50 year old debate? Genetic assimilation is a process whereby environmentally induced phenotypic variation becomes constitutively produced (i.e. no longer requires the environmental signal for expression). Although the origins of this concept can be traced [genetic assimilation] is an interesting but, I would judge, relatively minor outcome of the [synthetic] theory' ...
