Population of Pedroches Valley, a hypothetical Berber settlement, located in the northwest portion of Córdoba province (Andalusia, Spain), had been analyzed for its Y‐chromosome diversity. Moreover, to contextualize this population, 127 Y‐chromosomes from a general Andalusia sample and a North African Berber community (Marrakech, Morocco) were also typed. For all samples, 24 single nucleotide polymorphisms of the non‐recombining portion of the Y‐chromosome (NRY) were analyzed and those samples described as belonging to E3b1b‐M81 haplogroup were also typed for 16 Y‐chromosome short tandem repeats. Our Analysis showed low levels of North African E3b1b‐M81 haplogroup in the Pedroches Valley population (1.5%), which is a lower contribution than would be expected. This result rejects the hypothesis of a gradual genetic assimilation of Berber settlers during the Islamic period. Am. J. Hum. Biol., 2009. © 2009 Wiley‐Liss, Inc.
