We obtained point estimates of the TMRCA of two haplotypes by dividing the estimate of the number of mutational steps separating the haplotypes (as inferred from the network) by twice the mutational rate per STR and by the number of STRs scored in both haplotypes. Values above and below the diagonal separation correspond to estimates obtained with the high and low mutation rates, respectively (see text). The following abbreviation is used: TMRCA, time to the most recent common ancestor.

High mutation rate.

Low mutation rate.
