Significance of SNPs around association signals selected in Flyland and the DGRP. (A) SNPs within 10 kb of significant Flyland SNPs were tested for associations with each trait in Flyland. The same number of background SNPs (B) was randomly drawn from the genome and tested for associations with the traits. P values are from Wilcoxon tests of the difference between the level of significance in selected (S) and background (B) sets. Similar analyses were also performed for (B) SNPs selected around DGRP signals and tested in the DGRP, (C) SNPs selected around Flyland signals and tested in the DGRP, and (D) SNPs selected around DGRP signals and tested in Flyland.
