Estimates of ΦPT were calculated using 9 loci (excluding WF2C01, BEM6, BT-e49, BtIs1.2) on 132 samples from seven populations for biotype B and 11 loci (excluding BEM6, BT-b103) on 213 samples from 9 populations for biotype Q. Analyses within biotype Q were done on relevant subsets of the dataset, for Western and Eastern Mediterranean populations.
