The ontogeny of cross-sex genetic correlations: an analysis of patterns.

abstract：:Evolutionary theory predicts that divergent selection pressures across elevational gradients could cause adaptive divergence and reproductive isolation in the process of ecological speciation. Although there is substantial evidence for adaptive divergence across elevation, there is less evidence that this restricts ge...
