Evaluation of probabilities of the heritability ( h 2 ) estimates in full‐sib analysis falling outside the permissible limits [0,1] was undertaken for several combinations of sire/dam numbers, h 2 and proportions of dominance and additive × additive epistatic variances, assuming two full‐sibs per mating and the dominance related epistasis as negligible. In the light of the results use of sire component and sire‐dam combination has been recommended in the estimation of heritability of lowly and highly heritable traits respectively.
