The role of phenotypic plasticity on population differentiation.

ABSTRACT: Several evolutionary processes shape the genetic and phenotypic differentiation of populations. Among them, the joint effects of gene flow, selection and phenotypic plasticity are poorly known, especially when trying to understand how maladaptive plasticity affects population divergence. We extended a quantitative genetic model of Hendry et al. (2001) to describe these joint effects on phenotypic and additive genetic divergence between two populations, and their phenotypic and genetic differentiation (P_ST and Q_ST). With individual-based simulations, we tested our model predictions and further modeled allelic differentiation at neutral (F_ST) and adaptive (F_STQ) loci. While adaptive phenotypic plasticity allows for large phenotypic divergence and d
