    • "). Correspondence analysis in three dimensions and its bidimensional representation was carried out by using the VISTA v5.02 computer program (Young & Bann 1996 ; http :\forrest.psych.unc.edu ; Arnaiz-Villena et al. 1999, 2000 ; Gomez-Casado et al. 2000 b). Correspondence analysis consists of a geometric technique that may be used for displaying a global view of the relationships among populations according to HLA (or other) allele frequencies. "

    ABSTRACT: HLA class I and class II alleles have been studied for the first time in the Turkish-speaking Tuvinian population, which lives in Russia, North of Mongolia and close to the Altai mountains. Comparisons have been done with about 11000 chromosomes from other worldwide populations, and extended haplotypes, genetic distances, neighbor joining dendrograms and correspondence analyses have been calculated. Tuvinians show an admixture of Mongoloid and Caucasoid characters, the latter probably coming from the ancient Kyrgyz background or, less feasibly, more recent Russian Caucasoid admixture. However, Siberian population traits are not found and thus Tuvinians are closer to Central Asian populations. Siberians are more related to Na-Dene and Eskimo American Indians; Amerindians (from nowadays Iberian--America) are not related to any other group, including Pacific Islanders, Siberians or other American Indians. The 'more than one wave' model for the peopling of the Americas is supported.

    ABSTRACT: This work was supported in part by grants from the Spanish Ministry of Education (PM 57–95 and PM 96–21) and Comunidad de Madrid (06–70–97 and 8.3/14/98). Gilberto Vargas-Alarcón was supported by the Consejo Nacional de Ciencia y Tecnología and the Fundación Mexicana para la Salud, Mexico. The HLA allele frequency distribution of the Mexican Mazatecan Indians (Olmec culture) has been studied and compared with those of other First American Natives and worldwide populations (a total of 12,100 chromosomes; 6,050 individuals from 59 different populations). The main conclusions are: 1) An indirect evidence of Olmec and Mayan relatedness is suggested, further supporting the notion that Olmecs may have been the precursors of Mayans; 2) Language and genetics do not completely correlate in microenvironmental studies; and 3) Peopling of the Americas was probably more complex than postulated by Greenberg and others (three peopling waves). Significant genetic input from outside is not noticed in Meso and South American Amerindians according to the phylogenetic analyses; while all world populations (including Africans, Europeans, Asians, Australians, Polynesians, North American Na-Dene Indians and Eskimos) are genetically related. Meso and South American Amerindians tend to remain isolated in the Neighbor-Joining, correspondence and plane genetic distance analyses.

    ABSTRACT: Following the decision to hold their next full meeting after the 13th International Histocompatibility Workshop in 2002, the WHO Nomenclature Committee for Factors of the HLA System has decided to publish an interim report listing updated tables of alleles including those assigned since the publication of the last full report in 1999 (1). The alleles named during the period follow the principles established in previous reports (1-15).
