Figure 1

Schematic representation of the BSA index for the SNPs in the S. exigua unigenes with orthologs into the silkworm genome. Each data point (from 0 to 1) is the average index for three consecutive orthologs calculated using overlapping rolling-windows (BSA index for each unigene individually is provided in Additional file 3). Average index >0.60 are painted in red. BSA, bulk segregant analysis; SNPs, single nucleotide polymorphism.
