What if fitness & migration were random?

razib | November 11, 2009

There are many ways one can model population genetic dynamics. A simple avenue is to imagine a deme, a group of breeding individuals, subject to a few major parameters which are modulating genetic variation. Mutation, migration, random drift and selection. A model being what a model is, one's goal is to simplify, utilize approximations, and still manage to extract insight as to the relevant aspects of the dynamics one is focusing on (unless you're Stephen Wolfram). One of the major upsides of the Price Equation is that it makes no compromises, rather, it starts from first principles and…
