Note.— TMRCA estimates based on 8 STRs (DYS19, DYS388, DYS389b, DYS389I, DYS390, DYS391, DYS392, and DYS393) in nine North African populations (those from the present study and the Moroccan samples of Bosch et al. 2001). In these calculations, we incorporated the information from binary markers.
a
The two parameters describing the population growth (alpha and beta) have been set as alpha prior uniform (0.03, 0.05) and beta prior uniform (0.10, 0.20), the microsatellite mutation rates used were from Weale et al. (2001) or gamma (2,1000) for the loci for which published estimates of mutation rates were not available.
