Gene-culture coevolution under selection.

The joint evolutionary dynamics of phenotypes and genotypes are usually couched in terms of genetic variance contributions to changes in the phenotypic mean. Here, we study the evolution of a dichotomous phenotype whose transmission is controlled by one multi-allelic locus. The phenotype is under selection, which may be genotype-dependent. We answer classical population genetic questions about the phenogenotypic evolution, including the conditions for phenotypic and genotypic polymorphism, in terms of selection coefficients and rates of phenotypic transmission.
