Abstract

We analysed a 610-bp mitochondrial (mt)DNA D-loop fragment in a sample of German draught horse breeds and compared the polymorphic sites with sequences from Arabian, Hanoverian, Exmoor, Icelandic, Sorraia and Przewalski's Horses as well as with Suffolk, Shire and Belgian horses. In a total of 65 horses, 70 polymorphic sites representing 47 haplotypes were observed. The average percentage of polymorphic sites was 11.5% for the mtDNA fragment analysed. In the nine different draught horse breeds including South German, Mecklenburg, Saxon Thuringa coldblood, Rhenisch German, Schleswig Draught Horse, Black Forest Horse, Shire, Suffolk and Belgian, 61 polymorphic sites and 24 haplotypes were found. The phylogenetic analysis failed to show monophyletic groups for the draught horses. The analysis indicated that the draught horse populations investigated consist of diverse genetic groups with respect to their maternal lineage.

摘要

我们分析了德国挽马品种样本中的一段610个碱基对的线粒体（mt）DNA D环片段，并将多态性位点与阿拉伯马、汉诺威马、埃克斯穆尔马、冰岛马、索拉亚马和普氏野马以及萨福克马、夏尔马和比利时马的序列进行了比较。在总共65匹马中，观察到代表47种单倍型的70个多态性位点。所分析的mtDNA片段的多态性位点平均百分比为11.5%。在包括南德马、梅克伦堡马、萨克森图林根冷血马、莱茵兰德国马、石勒苏益格挽马、黑森林马、夏尔马、萨福克马和比利时马在内的九个不同挽马品种中，发现了61个多态性位点和24种单倍型。系统发育分析未能显示挽马的单系群。分析表明，所研究的挽马种群在母系谱系方面由不同的遗传群体组成。
