Extensive hybridization with minimal introgression in Mytilus galloprovincialis and M. trossulus in Hokkaido, Japan.

The article explores the significant role of extensive hybridization with minimal introgression in the environmental circumstances of Mytilus trossulus and Mytilus galloprovincialis that exists in Hokkaido, Japan. It examines the similarity of the pattern between in other observed geographic locations and in hybridize Mytilus trossulus and Mytilus galloprovincialis. It presents the two independent hybrid zones that has been produced in the country. Furthermore, it describes the genetic structures of the hybrid populations in the southern and eastern cost of Sea of Japan.
