✦ Synopsis

Summa y

Evaluation of probabilities of the heritability (h2) estimated in full-sib analysis falling outside the permissible limits [0,1] was undertaken for several combinations of sire/dam numbers, h2 and proportions of dominance and additive x additive epistatic variances, assuming two full-sibs per mating and the dominance related epistasis as negligible. I n 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.
