Metabolic profiles of selected subcongenics and their background strain, B6. Glucose (a), triglyceride (b), total cholesterol (c) and high density lipoprotein (d) in serum. Numbers of mice examined were: 9 males and 5 females for B6, 7 males and 7 females for B6.Cg-Pbwg1/SR4, and 8 males and 8 females for B6.Cg-Pbwg1/SR8 mice. Data are means ± SE. Star marks above the bars within a sex indicate a significant difference from B6 mice (**, P < 0.01; ***, P < 0.001, Dunnett's test).
