BECs at LORR recovery. a BECs at LORR recovery were higher in B6 than in F2. b Frequency histogram showing largely normal distribution (dashed line is normal distribution) in the F2 population. c A scan for single-locus main effects found two suggestive loci (P < 0.63, dashed black line), and a scan for single-locus sex interactions found another suggestive locus on Chr 9. d–g Allelic effects of the main-effect loci reveal under dominance on Chr 7 and a slightly positive dominance deviation on Chr 11. The sex difference is such that males had a lower LORR BEC than females, with male S1 homozygotes having the lowest LORR BEC; *P < 0.05. Data are mean ± SEM
