Enviado por Renata flag Denunciar. Remember that, for Wright, mass selection within demes is necessary for a ‘fitness’ peak.
In a recent tutuyma of Wright’s Shifting Balance Theory, using experimental arrays of the flour beetle, T. This is a level of migration that is often associated with significant genetic differentiation of demes but not with significant effects on the evolution of mean fitness.
Additional experiments indicate that there is a non- additive genetic basis for this response Wade, in preparation. The relationship between epistasis, adaptation, and Wright’s theory depends on a number of additional genetic and ecological features of natural populations.

However, despite these caveats, the role of gene interactions in adaptive evolution and the origin and spread of adaptations involving the coordinated action of many genes would be better understood if the kinds of empirical data discussed above could be obtained. Furthermore, the empirical predictions made here appear to be related directly to the evolutionary inferences regarding gene interactions drawn by Wright. By investigating the issues in these disputes, some general implications can be drawn and some novel experimental predictions for evaluating the role of gene interactions can be made.
The experimental investigation of these predictions may permit a more complete understanding of the evolutionary importance of gene interactions and the robustness of current theory that by and large ignores them. The ultimate test of Wright’s Shifting Balance Theory depends on empirical demonstration of the heterogeneity of genetic response to local selective pressures, the existence, density, and size of adaptive peaks, and the competence of interdemic selection by differential migration for exporting a favorable gene combination from one deme to the next.
