Analytical approaches usually assume a Gaussian distribution of trait values in the population, described by its mean and phenotypic variance (Lynch and Lande 1993; Gomulkiewicz and Holt 1995), while simulations determine individuals' trait values from a finite number of loci contributing specified effect sizes (Bürger and Lynch 1995; Boulding and Hay 2001).
