Abstract

Genetic variants at eight blood loci were analysed, disclosing in Andalusian breed six rare markers: variants J of transferrin, H of esterase, D and S of Xk, M and W of prealbumin. Two of these, TfJ and PrM appear as characteristic markers of Andalusian breed. Allelic frequencies showed minor differences between Spanish (300 horses) and Lusitanian (100 horses) populations. Comparison was established with historically related breeds, Thoroughbreds or Connemara, and with Arab horses because of a presumed relationship. No visible similarities in genetic profiles were found with two former breeds, nor with Arab horses. Unpredicted similarities were found however between Tarpans and Andalusian horses, appearing rather as convergences than witnessing a common ancestry.

摘要

对八个血液基因座的遗传变异进行了分析，在安达卢西亚马品种中发现了六个罕见标记：转铁蛋白的J变体、酯酶的H变体、Xk的D和S变体、前白蛋白的M和W变体。其中两个，即TfJ和PrM，是安达卢西亚马品种的特征性标记。等位基因频率在西班牙（300匹马）和卢西塔尼亚（100匹马）种群之间显示出微小差异。与历史上相关的品种，如纯种马或康尼马拉马，以及由于推测存在的关系而与阿拉伯马进行了比较。在基因图谱上未发现与前两个品种以及阿拉伯马有明显相似之处。然而，在 tarpans 和安达卢西亚马之间发现了意外的相似之处，这些相似之处更像是趋同现象，而非证明有共同的祖先。
