Phenotypic plasticity - Wikipedia
WebDec 22, 2024 · The phenotypic transformation of VSMCs in the body is often affected by a series of molecules and the integration of environmental factors, which mainly include lipids, retinoids, inflammatory mediators, growth factors, oxidative stress, blood flow shear stress, and cell-to-cell interactions. WebJun 8, 2024 · The result of this type of selection is a shift in the population’s genetic variance toward the new, fit phenotype. ... Diversifying selection can also occur when environmental changes favor individuals on either end of the phenotypic spectrum.

WebWhen "reinforcement-like" patterns are observed, one has to be sure that the phenotypic shift is actually an evolutionary response to the presence of the other incipient species and not to some other clinal variation (e.g., ecological factors that generate parallel clines). ...
