Table 2 Statistics for SNPs based on the two different methods

Method of SNPcalling	Raw SNPs	Clean SNPs	χ ² < 15
DISR^a	181,770	7457	3282
Based on reference genome	7,343,419	8664	5286

Shown are the number of raw SNPs, the number of SNPs remained after filtering and the number of SNPs by a Chi square test
