Última Estimation of variances of the effects of incomplete diallels using a matrix approach Genet. Mol. Biol. Assis,Giselle Mariano Lessa de; Fonseca,Ricardo da; Cruz,Cosme Damião; Carneiro Júnior,José Marques. A matrix approach is described for assessing the variance of effects in incomplete diallels designs. The method is illustrated by reference to simulated complete and incomplete diallels using different combinations of constraints, average degree of dominance and, for the incomplete diallel, number of hybrids. Our results showed that caution should be taken in working with incomplete diallels under conditions of overdominance because there were changes in the rank of the genotypes when the excluded hybrid had parents with a low frequency of the favorable allele (i.e. the allele which increases expression of a character). The expression described in this paper is a rapid and safe approach to estimate variances and covariances of the effects of contrasts of...
