Quantitative analysis of genetic differentiation among European and Chilean strains of Drosophila subobscura.

abstract：:Self-incompatibility (SI) has been well studied in the genera Brassica and Arabidopsis, which have become models for investigation into the SI system. To understand the evolution of the SI system in the Brassicaceae, comparative analyses of the S-locus in genera other than Brassica and Arabidopsis are necessary. We re...

It is known to exhibit patterns of geographical variation between populations, and has been suspected to consist of several very closely related species.
