LUGOVYE-MARIS - INBREEDING AND ENDOGAMY

The genetic structure of Lugovye Maris was studied on the basis of mar ital migration. Malecot's parameters of isolation and endogamy index w ere estimated in four raions of the Marii El Republic, which is popula ted by Maris. High values of the endogamy index (0.80 and 0.88) never observed previously in any Russian populations, were revealed in two r aions. The lack of significant correlation between endogamy and local inbreeding was analyzed. A significant correlation (0.70) between endo gamy and effective population size was revealed.
