Fourteen haplotypes were recognized. From the analyses of dendrogram (Fig. 1), the topology showed one cluster including 14 haplotypes, namely no clear genetic differences were found among these haplotypes. The results were considered to maintain that Japanese native horses have been originated from Korean peninsular rout reported by NOZAWA et el, not from 2 types and 2 routs reported by HAYASHIDA. From the constitution of haplotype analyses (Table 1), It was reveled that Kiso, Misaki and Taishu breeds are maintaining a high level of genetic diversity, on the other hand, Noma and Tokara breeds are losing diversity, and 8 breeds have clearly different haplotypes, respectively. For this reason, it can be estimated that each native breed has been kept within each feeding place for a long time., E, 6, KJ00005764604, 短報, Research Data}, pages = {211--213}, title = {日本在来馬のミトコンドリアDNA多型}, volume = {54}, year = {}, yomi = {カワシマ, シュウ and サッタ, ヨウコ} }
