The number, types, and consequences of polymorphic iMS loci genome-wide in the 1000 genomes Phase-1 dataset, by population group.

aThe number of loci is less than the total number of SNP and Indel interruptions because some loci contain multiple interruptions.bInterruptions resulting in iMS below the threshold length.cInterruptions resulting in iMS at/above the threshold length.

a. 位点（locus）的数量少于单核苷酸多态性（Single Nucleotide Polymorphism，简称SNP）与插入缺失变异（Insertion-Deletion，简称Indel）的中断事件总数量，原因在于部分位点包含多个中断事件。
b. 导致iMS低于阈值长度的中断事件。
c. 导致iMS达到或超过阈值长度的中断事件。
