1 DNA标记技术概述遗传标记(genetic markers)是分类学、育种学和物种进化研究的主要技术指标之一,是基因型(genetype)的特殊的易于识别的表现形式。当前遗传标记主要有4种类型:①形态标记(morphological markers)即生物的形态特征,如鱼的体色、体长、体高等;②细胞学标记(cyto
1 DNA marker technology overview Genetic markers are one of the main technical indicators of taxonomy, breeding and species evolution research. They are special recognizable forms of genetypes. The current genetic markers are mainly four types: ① morphological markers (morphological markers) that biological characteristics, such as body color, body length, body height; ② cytological markers (cyto
