Each chromosome is divided into 20 segments. Clicking on each of the numbered segments will bring up the SNPs for that segment in the second frame. The tick marks to the right of the chromosome indicates the relative SNP density in that region. Each SNP is identified by the clone and the position within that clone. One strain has the 'A' allele and the other strain has the 'G' allele.
Second column is the recognition site.
Third column has all the isoschizomers which recognizes with the patter in column two. N2 allele is always displayed first within the brackets.
