Conservation and change in the DNA sequences coding for alcohol dehydrogenase in sibling species of Drosophila.

abstract：:One of the most debated questions in evolutionary biology is whether female choice of males with exaggerated sexual displays can evolve as a correlated response to selection acting on genes coding for male attractiveness or high overall viability. To date, empirical studies have provided support for parts of this scen...
