摘　　要：DNA分子标记技术的出现,对动物遗传育种产生了深远的影响,利用DNA标记可以研究动物整个基因组水平的遗传变异,进行动物遗传资源研究、标记辅助选择、标记辅助导入、杂种优势预测、选配、品种与品系确认、构建高分辨率遗传连锁图谱、QTL搜寻定位等。目前在动物遗传中广泛使用的标记主要有mtDNA、RFLP、RAPD、AFLP、SSR、SNP和EST标记。本文综述了这些标记技术的原理、特点,并根据其特点,分析其在动物遗传育种中的应用,并通过维普数据库搜索比较分析研究者对各种技术的使用情况。The development of DNA-based genetic markers has had a revolutionary impact on animal genetics. With DNA markers, it is theoretically possible to observe and exploit genetic variation in the entire genome. Popular genetic markers in the animal community include mitochondrial DNA, RFLP, RAPD, AFLP, microsatellite, SNP, and EST markers. The application of DNA markers has allowed rapid progress in animal genetics and breeding. This review article is intended to provide a systematic introduction of DNA marker technologies and their relevant applications to the general audience working in animal genetics and breeding.
