title: North African genes in Iberia studied by Y-chromosome DNA haplotype 5.
abstract: The frequency of haplotype 5 at the Y-chromosome-specific DNA polymorphism (p49/TaqI) was reported in a study of 487 males originating from five different geographic locations in Iberia and North Africa. The highest frequency of haplotype 5 (68.9%) was previously observed in Berbers from Morocco, and it has been established that this haplotype is a characteristic Berber haplotype in North Africa. The relative frequencies of haplotype 5 distribution show a geographical gradient of decreasing frequency according to latitude in Iberia: 40.8% in Andalusia, 36.2% in Portugal, 12.1% in Catalonia, and 11.3% in the Basque Country; such a cline of decreasing frequency of haplotype 5 from the south to the north in Iberia clearly establishes a gene flow from North Africa towards Iberia.
