In addition, we determined the nucleotide sequences of cyt b from 13 specimens and reconstructed a phylogenetic tree. Our results showed that, in Yamagata prefecture, the wild populations of the Medaka fish were mainly divided into two groups: One group distributed in the northern coastal area and another distributed in the inland area. The boundary between those areas was detected in Mamurogawa-machi, Sakekawa-mura and Tozawa-mura. Key words: Geographic variation, Oryzias latipes, mitochondrial DNA,Yamagata prefecture.//佐々木,隆行/ササキ, タカユキ/Sasaki, Takayuki/渡辺, 明彦/ワタナベ, アキヒコ/Watanabe, Akihiko/鬼武, 一夫/オニタケ, カズオ/Onitake, Kazuo}, pages = {55--69}, title = {山形県内に生息する野生メダカにおける種内分化の分子遺伝学的解析}, volume = {16}, year = {2006} }
