遗传标记(genetic marker)是指用来区分不同的个体或群体,能够稳定遗传的物质或性状,是研究生物的遗传、进化及生态特征的重要工具。遗传标记的发展经历了形态标记、细胞学标记、同工酶标记和分子标记4个阶段。其中分子标记(molecularmark-er)也称DNA标记(DNA marker),是生物基 Genetic markers are used to distinguish between different individuals or groups, stable genetic material or trait, is an important tool to study the genetic, evolutionary and ecological characteristics of the organism. The development of genetic markers underwent morphological markers, cytological markers, isozyme markers and molecular markers in four stages. Molecular markers (molecular markers), also known as DNA markers (DNA markers), are bio-based
