Figure 4

Median-Joining network based on CR sequences. Each circle represents a haplotype and the sizes of circles correspond to the number of individuals sharing this haplotype. Colours indicate sampling site. Every crossbeam on the connecting lines between haplotypes represents a substitution. Small black dots between haplotypes symbolize hypothetic haplotypes not present in the data set. Blind individuals from either Ghubrat Tanuf or Wadi Falahi are indicated by shaded circles, intermediate individuals are indicated by circles filled with an asterisk.
