^aStudy 1: Radcliffe et al. 2004; Study 2: Radcliffe et al., 2006a.

^bPeak LOD; suggestive (*), significant (**).

^c95% confidence interval calculated using WinQTLCart (Wang et al. 2006).

^dLOD scores were combined using Fishers method (Sokal and Rohlf, 1981); scores were not combined for chromosome 12 because the 95% confidence interval for the two QTL did not overlap (Radcliffe et al., 2006a).
