Add: additive effect at each locus estimated as half the difference of the two homozygous genotypic groups.
Dom: dominance effect estimated as the deviation of heterozygous genotypic group from mid parental genotypes at each locus
: the proportion of phenotypic variance accounted for by each locus.
* and ** are significant at P < 0.05 and 0.01; ns: not significant at P < 0.05.
