Research Abstract

Genetic structures of three hybrid zones (Mt. Hakkoda, Mt. Zao and Mt. Tanigawa) were analyzed by using 34 marker loci mapped on a linkage-map in order to detect natural selection acting on the hybrid zones. Statistically significant deviations of allele frequencies were detected at4 marker loci consistently across all hybrid zones. It is suggested that natural selection would act on the 4 loci. Additionally, we found that the hybrid population in Mt. Zao showed the least level of linkage disequilibrium, suggesting that genetic fusion between the two parental species is highly developed in Mt. Zao.
