A 15-Myr-old genetic bottleneck.

Molecular biology and evolution - 1 Apr 2008

Paape Timothy, Igic Boris, Smith Stacey D, Olmstead Richard, Bohs Lynn, Kohn Joshua R

Abstract excerpt

Balancing selection preserves variation at the self-incompatibility locus (S-locus) of flowering plants for tens of millions of years, making it possible to detect demographic events that occurred prior to the origin of extant species. In contrast to other Solanaceae examined, SI species in the sister genera Physalis and Witheringia share restricted variation at the S-locus. This restriction is indicative of an...
