Facts
Y-chromosome haplogroups studies
- Two sister clades, J-M267 and J-M172, are distributed differentially within the Near East, North Africa, and Europe. (15069642)
- J-M267 was spread by two temporally distinct migratory episodes, the most recent one probably associated with the diffusion of Arab people. (15069642)
- E-M81 is typical of Berbers, and its presence in Iberia and Sicily is due to recent gene flow from North Africa. (15069642)
- J-M172(xM12) distribution is consistent with a Levantine/Anatolian dispersal route to southeastern Europe and may reflect the spread of Anatolian farmers. (15069642)
- E-M78 (for which microsatellite data suggest an eastern African origin) and, to a lesser extent, J-M12(M102) lineages would trace the subsequent diffusion of people from the southern Balkans to the west. (15069642)
- A 7%-22% contribution of Y chromosomes from Greece to southern Italy was estimated by admixture analysis. (15069642)
