    Journal: Exp Clin Immunogenet; 1988; 5(1):1-14. PubMed ID: 3155402.
    Abstract:
    The Gm, Am and Km allotypes have been investigated in 405 sera from unrelated students and blood donors coming from the different areas of Tunisia. Thirty Gm and fourty-seven Gm-A2m common phenotypes have been observed. Eleven Gm* and seventeen Gm*-A2m* common haplotypes have been deduced from these phenotypes. The Tunisian population appears as mainly Caucasoid (combined frequency of Caucasoid Gm*-Am* haplotypes in the order of 0.81-0.82) with a relatively important Black contribution in the gene pool (combined frequency of Negroid Gm*-Am* haplotypes of 0.17-0.18) and a very low Oriental participation (0.01-0.02). Our results are compared to those previously reported for two other samples of the Tunisian population, the first from the regions of Mahdia and Sfax and the second from several villages of Berbers, the first inhabitants of Tunisia. Likewise, other comparisons are made with populations from Africa, Europe and Asia, since Tunisians are a mixture of Berbers, invaders and immigrants from different origins.
