Two locus interactive effects in (B6 × TH) F2 male progeny. The associated phenotypic traits are hyperglycemia (A and B) and hypertriglyceridemia (C). Lines connect means ± SEM of the plasma glucose or triglyceride levels for one marker on the X axis as homozygous for B6 (B), heterozygous for TH and B6 (H) or homozygous for TH (T) associated with another marker homozygous for B6 (B, solid line), heterozygous for B6 and TH (H, dotted line) or homozygous for TH (T, dashed line).
