“…The estimates of F st are very sensitive to the mode of clustering of populations (Jorde, 1980) and there may be also variations depending on the number of loci analyzed. Despite these caveats, it is evident that the F st value we estimated (0.011) is approximately halfway between the European populations extremes (0.0002-0.0136; Jorde, 1980;Jorde et al, 1982) and the Indian castes (0.0438; Papiha, 1996) and the Yanomana (0.065; Ward, 1973). Furthermore, our value is lower than that calculated for all of sub-Saharan Africa (0.035; CavalliSforza et al, 1994).…”

This study analyzes the distribution of ten protein genetic polymorphisms in eighteen populations from the most densely inhabited areas of Cameroon. The languages spoken belong to three different linguistic families [Afro-Asiatic (AA), Nilo-Saharan (NS) and Niger-Kordofanian (NK)]. The analysis of variation of allele frequencies indicates that the level of genetic interpopulation differentiation is rather low (F(st) = 0.011 +/- 0.006) but statistically significant (p < 0.001). This result is not unexpected because of the relatively small geographic area covered by our survey. This value is also significantly lower than the one estimated for other groups of African populations. Among the factors responsible for this, we discuss the possible role of gene flow. There is a considerable genetic differentiation among the AA populations of north Cameroon as is to be expected because they all originated from the first agriculturists of the farming "savanna complex." The Podowko and Uldeme are considerably different from all the other AA groups, probably due to the combined effect of genetic drift and isolation. In the case of the Wandala and Massa, our analyses suggest that genetic admixture with allogeneous groups (especially with the Kanuri) played an important role in determining their genetic differentiation from other AA speaking groups. The Bantu speaking populations (Bakaka, Bamileke Bassa and Ewondo, NK family, Benué Congo subfamily) settled in western and southern Cameroon are more tightly clustered than AA speaking groups. This result shows that the linguistic affinity among these four populations coincides with a substantial genetic similarity despite their different origin. Finally, the Fulbe are genetically distinct from all the populations that belong to their same linguistic phylum (NK), and closer to the neighboring Fali and Tupuri, eastern Adamawa speaking groups of north Cameroon.

We have analysed data of three European populations speaking non-Indoeuropean languages: Hungarians, Lapps, and Finns. Principal coordinate analysis shows that Lapps are almost exactly intermediate between people located geographically near the Ural mountains and speaking Uralic languages, and central and northern Europeans. Hungarians and Finns are definitely closer to Europeans. An analysis of genetic admixture between Uralic and European ancestors shows that Lapps are slightly more than 50% European, Hungarians are 87% European, and Finns are 90% European. There is basic agreement between these conclusions and historical data on Hungary. Less is known about Finns and very little about Lapps.

Biochemical genetic data from 3272 individuals from the Aland Islands, Finland, are analyzed using a recently developed set of nonparametric genetic distance measures. These measures are more robust than the traditional methods used in previous studies of this population. While there was general agreement in the results of the traditional and nonparametric approaches, some important differences were seen. In these cases, the nonparametric methods gave result more congruent with population history, geographic pripinquity, and migration patterns. Heterozygosity measures were also calculated for the Aland Islands population and compared to values obtained for Jewish populations. The total heterozygosity values were very similar.
