摘要

The long-standing goal of finding genes causing reproductive isolation is being achieved. To better link the genetics with the process of speciation, we propose that ‘speciation gene' be defined as any gene contributing to the evolution of reproductive isolation. Characterizing a speciation gene involves establishing that the gene affects a component of reproductive isolation; demonstrating that divergence at the locus occurred before completion of speciation; and quantifying the effect size of the gene (i.e. the increase in total reproductive isolation caused by its divergence). Review of a sample of candidate speciation genes found that few meet these criteria. Improved characterization of speciation genes will clarify how numerous they are, their properties and how they affect genome-wide patterns of divergence.
