Mitochondrial DNA analysis of Tunisians reveals a mosaic genetic structure with recent population expansion
Genetic variation in Tunisia in the context of human diversity worldwide
OBJECTIVES: North Africa has a complex demographic history of migrations from within Africa, Europe, and the Middle East. However, population genetic studies, especially for autosomal genetic markers, are few relative to other world regions. We examined autosomal markers for eight Tunisian and Libyan populations in order to place them in a global context. MATERIALS AND METHODS: Data were collected by TaqMan on 399 autosomal single nucleotide poly…
An investigation of the genetic diversity of the Kerkennah islands and Mahdia (Tunisia) using biparental markers
The strategic location of the two studied populations and their fortifications have allowed them to play a leading role in the Mediterranean basin
Human Alu Insertion Polymorphisms in North African Populations
Several features make Alu insertions a powerful tool used in population genetic studies: the polymorphic nature of many Alu insertions, the stability of an Alu insertion event and, furthermore, the ancestral state of an Alu insertion is known to be the absence of the Alu element at a particular locus and the presence of an Alu insertion at the site that forward mutational change. This study analyses seven Alu insertion polymorphisms in a sample o…
Ancient Local Evolution of African mtDNA Haplogroups in Tunisian Berber Populations
Our objective is to highlight the age of sub-Saharan gene flows in North Africa and particularly in Tunisia. Therefore we analyzed in a broad phylogeographic context sub-Saharan mtDNA haplogroups of Tunisian Berber populations considered representative of ancient settlement. More than 2,000 sequences were collected from the literature, and networks were constructed. The results show that the most ancient haplogroup is L3*, which would have been i…
Post‐last glacial maximum expansion from Iberia to North Africa revealed by fine characterization of mtDNA H haplogroup in Tunisia
The first large‐scale fine characterization of Tunisian H lineages clarifies that the post‐Last glacial maximum expansion originating in Iberia not only led to the resettlement of Europe but also of North Africa. We found that 46% of 81 Tunisian H lineages subscreened for 1,580 bp in mtDNA coding region were affiliated with H1 and H3 subhaplogroups, which are known to have originated in Iberia. Although no signs of local expansion were detected, …
