(a) The estimated bias decreases with body size (P = 0.040, partial R² = 3.6%), (b) increases with heterozygosity (P < 0.001, partial R² = 11.3%), and (c) with the percentage change in registration numbers (P < 0.001, partial R² = 34.2%). (d) Breeds with higher heterozygosity showed a stronger percentage increase in registration numbers (P < 0.001, partial R² = 51.2%). Depicted are predicted values with 95% confidence intervals and partial residuals accounting for the effect of the other variables in the regression models (n = 119)
