LewinFor all traits except the cold pain threshold, the cross-twin correlations were higher in MZ than in DZ twins. Significant heritability estimates could be calculated for cold (A) and warmth (B) detection thresholds, whereas for the heat (C) and cold (D) pain thresholds, the CE model, not containing a heritable component, was preferred. r, intra-class correlation; h2, heritability estimate; 95% confidence interval in brackets; AE/CE, preferred model used to estimate heritability.
