No signifi cant differentiation was observed in the total loci set, indicating close genetic relationship between the three Eastern Slavic peoples in forensic autosomal STR loci. <...> The three samples demonstrate a low level of genetic differentiation: estimates of genetic distance (Nei, 1978) between the samples lie in the 0.9968–0.9990 interval, and average Fst equals 0.0240 for the 18 loci. <...> Lower values of observed heterozygosity compared to expected heterozygosity are caused by migration fl ow within the main ethnic group to the population of the megalopolis from other subdivided populations, demonstrating the Wahlund effect. <...> Peculiarities of genetic and demographic parameters of the three megalopolises are discussed in the context of the problem of forensic genetic databases formation (autosomal STR, mitochondrial and Y chromosome markers) for mixed populations. <...> A more intense male migration suggests more signifi cant dynamics of genetic markers of Y-chromosome, compared to mitochondrial DNA markers. <...> For the forensic genetic database of Minsk it is important that the main migration fl ow comes from the territory of Belarus and consists of ethnic Byelorussians with low migration from Russia or Ukraine. <...> Key words: forensic genetic database, STR loci, megalopolis, mixed population, genetic-demographic parameters, migration, gene fl ow Contact information: Udina Irina, e-mail: irina_udina@mail.ru. <...> EARLY MEDIEVAL COPTS OF THE FAYOUM OASIS, EGYPT: AN ANTHROPOLOGICAL STUDY Vasilyev Sergey Institute of Ethnology and Anthropology, Russian Academy of Sciences, Moscow, Russia This study deals with skeletal remains of the early medieval Copts from the necropolis of Deir el-Naqlun, the Fayoum Oasis, Egypt. <...> That these skeletons and mummifi ed bodies are indeed Coptic follows from the fact that they were found during excavations at the territory of a Coptic monastery and there were some elements of Coptic monastic garments on many of them. <...> We studied 30 skulls using the standard craniological program. <...> Twenty of them belonged to males and ten to females. <...> The cranial index is average and most male skulls tend to mesocrany. <...> Height indices of the braincase suggest that male skulls are medium high. <...> The facial skeleton of males is relatively narrow (lepten). <...> The orbital index is average and so are nasal dimensions. <...> The horizontal facial profi le in males is <...>
