2b - RAD is based on type II B restriction enzymes (Nature of the Methods (wang et al, 2012)). The technology overcomes some shortcomings of RAD-Seq and GBS. It provides 33-36 bp enzyme label, sequencing after label enrichment to achieve SNP screening and genotyping analysis from whole genome wide range.

Technical characteristics
1.Strong flexibility, tag number is under control
2.The label length is consistent, with a consistent PCR amplification efficiency
3.Position specificity in labels, does not depend on the reference sequence and assembly result
4.Codominant markers SNPS is available, also can make use of dominant markers
5.Based on mixed poisson distribution model of de novo SNP classification (iML), which can remove the distraction of repetitive sequence effectively. Classification accuracy is better than existing algorithms, with a false positive rate is lower 20%.
