Allele frequencies of six non-synonymous SNPs associated with field-evolved Cry1Fa-resistance in Ostrinia nubilalis for the (a) survived exposure to non-treated control, (b) died after exposure to diagnostic concentration (200 ng Cry1Fa cm−2), and (c) survived exposure to diagnostic concentration (200 ng Cry1Fa cm−2) of the F2BC-RxON-S1 as determined using restriction enzyme digests. Black, grey, and white bars indicate homozygotes for the alleles associated with Cry1Fa susceptibility (p2), heterozygotes (2pq), and homozygotes for the alleles associated with Cry1Fa resistance (q2), respectively.
