The Sart Kalmyks rarely became the object of bioanthropological research. <...> The few studies include that by D.O. Ashilova (1976), who made a number of conclusions based on anthropometric data. <...> Though the ethnographic group of Sart Kalmyks incorporated into the Kirghiz nation in the past was related to the Western Mongolian ethnic group by common ancestry, language, and culture, now they differ in appearance from groups belonging to the Central Asian anthropological type (Kalmyks, Mongols, and Buryats) and show the closest affi nity with Kirghizes. <...> During our expedition in 2013, we conducted a comprehensive anthropometric and genetic study among the Sart Kalmyks. <...> We have collected anthropometric data on 84 women and 119 men, made 830 photographs for creating generalized portraits, and studied the diagnostically important descriptive characteristics of the face. <...> Regarding ethnicity, the following distribution was observed: 111 persons stated that both their parents were Sart Kalmyks, and about a half of them (51 persons) knew the tribal affi liation of parents. <...> Key words: physical anthropology, anthropometry, population history, Sart Kalmyks Contact information: Balinova Nataliya, e-mail: balinovs@mail.ru, Khomyakova Irina, e-mail: irina-khomyakova@yandex.ru. <...> GENETIC DIVERSITY AND LINKAGE DISEQUILIBRIUM PATTERNS IN ROMA POPULATIONS LIVING IN CROATIA BASED ON X CHROMOSOME STR LOCI Barešić Ana, Peričić Salihović Marijana, Janićijević Branka Institute for Anthropological Research, Zagreb, Croatia The aims of the study were to evaluate the genetic diversity and explore linkage disequilibrium (LD) patterns in three Roma populations of different migration origin, socio-cultural and dialect category using seven microsatellite (STR) loci in the Xq13.3 region of the X chromosome. <...> These loci (DXS983, DXS8037, DXS8092, DXS1225, DXS8082, DXS1066 and DXS986) were analyzed in 189 Roma males from three populations in Croatia (Međimurje, Baranja and Zagreb), who belong to different migration and dialect groups. <...> Several diversity indices (e.g. gene diversity, expected heterozygosity, mean number of pairwise differences) were calculated and the level of LD was inferred using exact test and D’ statistics. <...> Results suggest that Međimurje Roma population has the lowest genetic diversity (π = 4.756) and is signifi cantly different <...>
