Cline analyses for microsatellites and mtDNA sequences across the two transects running through Baden-Württemberg (top). The red dots in the maps represent the cline centres. The Maximum Likelihood clines are shown for Q values of cluster membership (microsatellites, centre) and the mitochondrial identity (bottom) of samples. Grey indicates the fuzzy cline regions (95% credibilities). Note the steep and concordant clines for both marker systems.
