Spatial genetic analyses defined two groups of populations, ‘‘western’’ and ‘‘eastern’’. The western populations had significantly lower genetic diversity in both markers and they face to higher level of fragmentation. One allele of the DRB gene predominated in the western group, four alleles were found in the eastern one. Population differentiation was high, but similar in both groups. Comparison of genetic variability and structure on microsatellites and MHC gene does not provide any evidence for contemporary selection on MHC gene. Genetic drift in small bottlenecked and fragmented populations may overact the role of balancing selection. Crossbreeding between the western and eastern populations should be done to reduce the risk of inbreeding depression in the western populations.
