  1. Bands are scored using the relaxed threshold of ≥2 for presence of a broken band and using the stringent threshold for presence of a broken band (scoring methodology detailed in methods). In bold are chi-square P-values for the two scoring methods showing significant deviation from the expected ratio (3:1 for F2 cross; 1:1 for backcross) for a phenotype (unbroken:broken) controlled by a single Mendelian locus. B10 and B14 were used for the QTL analysis
