Histogram showing distribution of traits at 24 weeks of age in F2 mice. We interbred TH mice with B6 mice, and the resultant F2 mice (male) were phenotyped at 8, 12, 16, 20, and 24 weeks of age for 4-hour fasting plasma triglyceride, total cholesterol, insulin, and glucose levels and body, fat pad and carcass weights. Count is the number of mice.
