• 一般注記: 出版タイプ： VoR; The presence of wild species of Bos is the feature of the genetic resources of cattle in Asia. The wild species of Bos consist of banteng (B. banteng), gaur (B. gaurus), yak (B. mutus), and kouprey (B. sauveli). There are some domesticated forms of these wild species, for example, domestic gaur (gayal or mithan) in hills of separate India, Bhutan, Myanmar and Bangladesh, domestic yak in Nepal to highland China, and domestic banteng (Bali cattle) in Indonesia. It is possible that domestic cattle in tropical and subtropical Asia have acquired some genes from such wild species, because they can interbreed with domestic cattle and, though mostly male offspring are sterility, female hybrid has breeding capability. However, it has been thought that the genetic influence from these wildness kinds is limitation-like, because the domestic forms of wild Bos species are distributed only over the area restricted extremely now. Thus. the native cattle in South and Southeast Asia was generally regarded as humped cattle (Zebu, indicus) or crossbred between humpless (taurus) and humped cattle in various rates. The hemoglobin β chain (Hbb) polymorphism is one of the most intensively investigated genetic characters in cattle. In Southeast Asia, most of the cattle populations were polymorphic with three electrophoretic bands : Hbb-A, -B, and -X with the three alleles, A, B, X at Hbb locus. The Hbb-X exists in the cattle of the Southeast Asia specifically, and is contained by 10 to 30% of gene frequency. When analyzed by using isoelectrofocusing method, the Hbb-X band can be further divided into two polymorphic bands, we temporarily call them X_1 and X_2 from the higher PI. The X_1 band was confirmed to be identical with the Hbb of mithan, on the other hand, the X_2 band showed no difference in the pI from the previous X (XBali) band of Bali cattle. In the continental part of Southeast Asia, the X_1 is far common compared with X_2. In this paper, we analyzed the DNA sequence of the bovine β globin alleles and found some evidence that there were large gene flow between wild species and domestic cattle in Southeast Asia.; P(論文); 特集; application/pdf; FEATURE ARTICLES
