Figure 2 : A neighbor-joining tree of individual similarities, based on 60 STR polymorphisms72, 100 Alu insertion polymorphisms21 and 30 restriction site polymorphisms73.

The percentage of shared alleles was calculated for all possible pairs of individuals, and a neighbor-joining tree was formulated using the PHYLIP software package74. African individuals are shown in blue, European individuals in green and Asian individuals in orange.
