ABSTRACT
The origin of genes in Talysh population (South Azerbaijan Republic) is considered. During 11 generations of population history more than 100 unrelated persons supplied the genes to the population. At present, the population is highly isolated: the endogamy index is 0.878, gametic index being 0.935. Inbreeding is estimated both ty means of genealogy and from the frequency of marriages between the persons of the same kin. The inbreeding coefficient is FIT = 0.026-0.030, its random component is FST = 0.01-0.02 and non-random component is FIS = 0.026-0.020.

Investigation was carried out in Talysh population in mountain region of South Azerbaijan. There is extended reproduction in the population. From XVIII till the beginning of XX century there were 3-3.6 offsprings in a family. In the last generation with completed reproduction, the family size raised to 7.13. Modern factors of population size dynamics are considered. It turned out that the main new factor (in conditions of increased family size) is the intensive migration from the population, mainly in men, that results in transformation of sex index in the reproductive age (ratio men/women is 0.77), and a large part of women stay unmarried. Crow index is Itot = 0.426, its components are Im = 0.115, If = 0.260.
