[Barrai's parameters for the Kirov oblast population and their geographic distribution].

The distribution of surnames in for populations of the district rank in Kirov oblast has been used to calculate Barrai's parameters, which are the following: Ir, 0.0008-0.0208; H, 6.

[Surname distribution and random inbreeding in Kirov oblast].

Data on surname distribution in 24 rations of Kirov oblast with a total adult population of more than 785000 people were used to calculate the random inbreeding values for populations of the district and rural municipality levels and analyze the geographic distributions of these values. The data have been compared with the results of studies carried out in the 1980s.

[Genetic epidemiological study of Bashkortostan Republic: the effect of genetic structure of population on the load of monogenic hereditary diseases].

Here we present the data obtained during medical genetic examination of the population of five districts of Bashkortostan Republic (Burzyanskii, Baimakskii, Abzelilovskii, Salavatskii, and Arkhangelskii) populated with 168050 persons including 135748 Bashkirs. The study involved all the population of the districts including each ethnic group and was conducted according to standard protocol developed in the Laboratory of Genetic Epidemiology, Medical Genetic Research Center, Russian Academy of Medical Sciences. Based on segregation analysis, the values of prevalence rates of the major types of Mendelian pathology (AD, AR, and X- linked diseases) was calculated in five regions of the Republic as well as for Bashkirs alone.

[Marriage migration parameters in six rural districts of Bashkortostan Republic].

The marriage migration structure of the populations of six districts of Bashkortostan Republic has been studied. The rates of assortative marriages in Bashkirs, Tatars, and Russians are 1.02-2.

[Analysis of reproductive and age parameters in Kalmyk rural populations].

Questionnaire data of 704 women of postreproductive age were used in this study. Questionnaire involved 462 Kalmyks, 119 Russians, 43 Kazakhs, 52 representatives of Northern Caucasus ethnic groups and, 28 other ethnic groups. The average number of pregnancies in Kalmyks was 5.

[Analysis of population genetic structure of ten district populations of the Rostov oblast by means of an extended isonymic method of Barrai and colleagues].

Parameters suggested by Barrai et al. (1992), including the random isonymy (I(r)), surname diversity (alpha), migration index (nu), and entropy (H) and redundancy (R) of surname distribution have been estimated in ten district populations of the Rostov oblast. Their weighted mean values are the following: I(r) = 0.

[Endogamy index and its changes with time in some populations of the Volga-Ural region].

Data on several populations of Russia have been used to demonstrate that the change in the endogamy index detected in the second half of the 20th century is not global. Migration activity remains high in populations with relatively low endogamy indices, and their endogamy does not change with time. In regions with medium and high endogamy indices, these values also tend to remain stable.
