Figure 3.—

Box and whisker plots of total worker ovariole number for the crosses between AHB and EHB that revealed the extreme ovariole number phenotype. From left to right is the AHB parent (A; shown as colony A2 in Figure 2), inbred AHB (AI 1–4), backcross AHB (ABC 1–8), hybrid (ExA), backcross EHB (EBC 3–10), inbred EHB (EI 1–3), and the EHB parent (E; shown as colony E10 in Figure 2). AHB backcross colonies ABC3 and ABC5 with extreme ovariole number phenotype were used for selective pooled DNA QTL mapping.
