WebGenetic analyses of both African and non-African populations have detected signatures of balancing selection at the TAS2R38 locus, including an excess of intermediate-frequency variants, a low amount of genetic differentiation between the continental populations (F ST = 0.056), and an ancient divergence between the major taster and nontaster haplotypes . Although North Africa has experienced gene flows from the surrounding regions, it has also experienced long periods of genetic isolation, allowing a distinctive genetic "Berber marker" to evolve in the native Berber people, as well as the "Coptic marker" among Egyptian Copts.
