Sample Description: This sample was collected by Dr.Lotfi Cherni and consists of unrelated individuals that are primarily of Berber ancestry from Mehdia, Central Tunisia. Mehdia is an inland city of central Tunisia founded in Roman times. It is located in the Mahdia governorate of modern Tunisia.The impact of the Arab Bedouin invasion beginning fourteen centries ago was relatively weak in the region of Mehdia.
