Abbreviations: CI, credibility interval; SE, standard error.
^aMedian for silent sites.
^b95% credibility intervals for θ.
^cLeast-squares estimate of ρ.
^dTajima's D test based on all sites.
^eFay and Wu H test.
^fNorth: Finland North, Finland South and Sweden.
^gCentral: Poland, France and Austria; ‘—’ not estimated because of the low sample size (∼5 for each locus) and low number of informative sites from each population.
^*P<0.05, statistical significance determined by coalescent simulations with and without recombination (see Materials and methods).
