  1. The ‘Small’ column gives the population mean ID in the Small population. The ‘Diff.’ is the difference between the mean δ in the Small population minus that of the Large population, and ‘s.e. (Diff)’ is the standard error hereof. The symbols σ2p, σ2m and σ2å are paternal, maternal and residual variances, respectively. The levels of statistical significance are ***P<0.001; **P<0.01; *P<0.05.
