In this paper we have studied the linear correlation between a genetic distance index between two parent lines (based on marker loci information) and the heterosis observed in the F1 hybrid from the two lines, for a quantitative character (determined by several loci, or QTL).

The relationship between heterozygosity at neutral marker loci and heterosis of F1 hybrids is investigated using a theoretical model. Results emphasize that linkage disequilibrium between the markers and the loci implicated in heterosis [quantitative trait loci (QTLs) that exhibit dominance effects]
Haploid male and diploid female honey bees, Apis mellifera, from colonies headed by queens polymorphic at the malate dehydrogenase (MDH) locus were examined for the influence of MDH genotype and heterozygosity on the size and asymmetry of six morphological characters. Although there were significant
