1 Polygenic and residual variances for each trait were estimated using genome-wise model (MCMC method) with or without fitting SNP effect in the model and presented as proportional to the polygenic and residual variances estimated using ASReml.

2 Polygenic and residual variances for each trait were estimated using ASReml and used for estimating heritability, .
