[The structure of the inbreeding coefficient in a rural Asian population]

The population-genetic study of an elementary rural population located in the Urgut district of Samarcand province was carried out. The pedigree for the whole population starting from the founders was evaluated. From 208 marriages presented in the population, 148 (71.2%) were consanguineous. The mean coefficient of inbreeding calculated from the pedigree was 0.028. A new approach to the evaluation of marital assortativity in a rural Uzbek population without tribial differentiation and inherited surnames was proposed. It consists in awarding artificial surnames to the founders of the population. Applying this approach to the population under study gives following values of F-statistics: FIT = 0.031, FIS = 0.01841, FST = 0.01282.
