Twenty enzyme loci were investigated using starch gel electrophoresis in managed populations of red deer (Cervus elaphus) and sika deer (C. nippon) from Ireland. The red deer, which originated from several European countries, were polymorphic (%P) at 25% of the loci examined and exhibited a mean heterozygosity (H) of 0.025. The sika, originally from Japan, were introduced to Ireland in very limited numbers. Here, %P was 5% and H was 0.006. Mean genetic distance (D) between these taxa was 0.160. Because Scottish red deer, the source of much of the Irish herd, had previously been investigated for 16 of the same enzyme loci, it was possible to merge the present data with results from that earlier study, which also included North American wapiti (C. elaphus canadensis). The resulting phenogram based on genetic distance demonstrates that sika are twice as distantly related to red deer and wapiti, than the latter are to each other and suggests that sika-like forms are ancestral. Also, the demonstration of absolute mobility differences in the products of two enzyme loci in red deer and sika has many practical applications.
利用淀粉凝胶电泳对来自爱尔兰的马鹿（Cervus elaphus）和梅花鹿（C. nippon）人工养殖群体中的20个酶位点进行了研究。起源于几个欧洲国家的马鹿，在所检测位点中有25%呈多态性（%P），平均杂合度（H）为0.025。原产于日本的梅花鹿，被少量引入爱尔兰。在此，%P为5%，H为0.006。这些分类单元之间的平均遗传距离（D）为0.160。由于爱尔兰马鹿群体的来源大多是苏格兰马鹿，之前已对其中16个相同的酶位点进行过研究，因此有可能将目前的数据与早期研究结果合并，早期研究还包括北美马鹿（C. elaphus canadensis）。基于遗传距离得出的系统树表明，梅花鹿与马鹿和北美马鹿的亲缘关系是马鹿与北美马鹿之间亲缘关系的两倍，这表明类似梅花鹿的形态是祖先形态。此外，马鹿和梅花鹿两个酶位点产物的绝对迁移率差异的证明有许多实际应用。
