Genetic variation at seven microsatellite DNA loci was quantified in 19 herds of wild caribou and domestic reindeer (Rangifer tarandus) from North America, Scandinavia and Russia. There is an average of 2.0-6.6 alleles per locus and observed individual heterozygosity of 0.33-0.50 in most herds. A herd on Svalbard Island, Scandinavia, is an exception, with relatively few alleles and low heterozygosity. The Central Arctic, Western Arctic and Porcupine River caribou herds in Alaska have similar allele frequencies and comprise one breeding population. Domestic reindeer in Alaska originated from transplants from Siberia, Russia, more than 100 years ago. Reindeer in Alaska and Siberia have different allele frequencies at several loci, but a relatively low level of genetic differentiation. Wild caribou and domestic reindeer in Alaska have significantly different allele frequencies at the seven loci, indicating that gene flow between reindeer and caribou in Alaska has been limited.
对来自北美、斯堪的纳维亚和俄罗斯的19群野生驯鹿和家养驯鹿（驯鹿属）的7个微卫星DNA位点的遗传变异进行了量化。每个位点平均有2.0 - 6.6个等位基因，大多数鹿群中观察到的个体杂合度为0.33 - 0.50。斯堪的纳维亚斯瓦尔巴德岛上的一群鹿是个例外，其等位基因相对较少且杂合度较低。阿拉斯加的中北极、西北极和豪猪河驯鹿群具有相似的等位基因频率，构成一个繁殖种群。阿拉斯加的家养驯鹿起源于100多年前从俄罗斯西伯利亚移植而来。阿拉斯加和西伯利亚的驯鹿在几个位点上具有不同的等位基因频率，但遗传分化水平相对较低。阿拉斯加的野生驯鹿和家养驯鹿在这七个位点上具有显著不同的等位基因频率，这表明阿拉斯加驯鹿和野生驯鹿之间的基因流动受到限制。
