Molecular evolution of genetic sex-determination switch in honeybees
Date:12/30/2013

n the beesthe switch that determines the shift from female to not female," said Page.

The authors also discovered a natural evolutionary intermediate that showed only three amino acid differences spanned the balance between lethality and induced femaleness. These findingswhich have taken nearly 200 years of study to pin downsuggested that incomplete penetrance may be the mechanism by which new molecular switches can gradually and adaptively evolve.

In addition to Beye and Page, authors included Christine Seelmann and Tanja Gempe with the University of Duesseldorf, Martin Hasslemann with the Institute of Genetics at the University of Cologne in Germany, Xavier Bekmans with Universit Lille in France and Kim Fondrk with Arizona State University. The work was supported by grants from the Deutsche Forschungsgemeinschaft.

Provost Page is the Foundation Chair of Life Sciences at ASU, a professor in the School of Life Sciences and the author of "The Spirit of the Hive: The mechanism of social evolution" published by Harvard University Press in 2013.
