Population differentiation between caves of Cave Bearsa.

aTop right: line 1, in parentheses, number of polymorphic sites in the pairwise alignment; lines 2 and 3, Nei's net distances Da, line 2 uncorrected; line 3 corrected for heterochrony with equations (1) and (3). Bottom left: P values from permutation tests, significance level; line 1 neglecting heterochrony; line 2 taking it into account; line 3 including uncertainty; line 4: Inter-population average pairwise time difference (KY). The number of sequences used for each population is given in parentheses at the top of the columns.b, cVariable number of sequences depending on the alignment chosen to maximize information.bn = 20.cn = 6.
