定义 主要指基因组水平上由单个核苷酸的变异所引起的 DNA 序列多态性. 在基因组水平上由单个核苷酸的变异所引起的DNA序列多态性.即:在不同个体的同一条染色体或同一位点的核苷酸序列中,绝大多数核苷酸序列一致而只有一个碱基不同的现象. 首先来看看多态性(polymorphism)的英文解释 Polymorphism the quality or state of existing in or assuming different forms: such as: a variation in a
1,软件介绍 FreeBayes is a Bayesian genetic variant detector designed to find small polymorphisms, specifically SNPs (single-nucleotide polymorphisms), indels (insertions and deletions), MNPs (multi-nucleotide polymorphisms), and complex events (composite
