∗Correlations that are significantly different from 0 at 𝑃<0.05.
HDL: high density lipoprotein; GLU: glucose; SBP: systolic blood pressure; TG: triglycerides; WC: waist circumference.
Each pair of traits is characterized by 4 types of within-individual correlations in fathers (𝜌_F), in mothers (𝜌_M), in sons (𝜌_S), and in daughters (𝜌_D).
