Fragments amplified from alleles of the Culex quinquefasciatus cqm1 gene. PCR produces profiles of homozygous for cqm1 (lane 1), heterozygous for cqm1REC (lane 2), homozygous for cqm1REC (lane 3), heterozygous for cqm1REC-D16 (lane 4), homozygous for cqm1REC-D16 (lane 5), and homozygous for cqm1REC-D25 (lane 6). No fragments were amplified from samples with Aedes aegypti DNA (lane 7) or without DNA (lane 8). Molecular size markers (molecular weight [MW]) in base pairs are shown on the left.
