Fig 5. DvSnf7 dsRNA resistant locus is located on LG 4.

Reciprocal single parent crosses were made between WCR-R and WCR-S beetles. Families A1, A2, and A5 contained a male WCR-R parent whereas families B6 and B9 contained a female WCR-R parent. F₂ individuals surviving on DvSnf7 or NT maize from each of five families were genotyped using the WCR SNP genotyping platform. Each panel represents one of the ten WCR linkage groups (LG). Within each LG, markers are ordered based on their genetic map position. The y-axis gives the χ² test statistic between the genotypic counts among F₂ populations surviving maize expressing DvSnf7 dsRNA or a non-transgenic control. Results from each of the five mapping families are plotted using a separate color following the legend above the figure. A black horizontal line on each panel indicates the Bonferroni threshold of 21.8.
