This is the fruit of the project that I discuss in the post Genetic basis of adaptive phenotypic branching. I have also posted two presentation on this project, a set of slides I used for a lab meeting at CADMS a while back and a poster that was presented at the Genetics of Speciation symposium (American Genetics Association Annual Symposium) at University of British Columbia in 2006 (see Presentations).

One basic question remains, however. When a population has undergone a branching in its phenotype, is this due to evolutionary branching in the underlying genotype or due to phenotypic plasticity modifying a single genotype? Together with Richard Svanbäck at Uppsala University and Michael Doebeli at University of British Columbia I am studying the conditions under which a predator phenotype experiencing selection for two alternative optimal phenotypes gives rise to genetically based phenotypic branching or to phenotypic plasticity. ]]>
