Results of tests for neutrality and population expansion given two different evolutionary scenarios for A) A. germinans and B) A. schaueriana based on microsatellite, cpDNA and nDNA markers. The values of Tajima’s D (Tajima, 1989); Fu and Li’s D* and F*(Fu & Li, 1993); the raggedness index (Rogers & Harpending, 1992); and Fu’s FS (Fu, 1997) are shown. The values in italics indicate P < 0.02 for FS and P < 0.05 for the remaining statistics.
