โœฆ Synopsis

Formulae are derived for the probability of obtaining negative eetimatsa of heritability (h2) in full-sib analysis under the additive-dominance-epietesie model of gene action. Evaluation of the probabilities was undertaken for several combinations of sire/dam number, h2 and proportiona of dominance and additive Xadditive epistatic variencea, assuming two full-ribs per mating and that the dominance related epistaaii is absent. In the light of the reaulta, minimum sample sizes for obtaining a d d i b l e estimates from sire, dam components and their combination have been prescribed.
