Molecular heterosis occurs when subjects heterozygous for a specific genetic polymorphism show a significantly greater effect (positive heterosis) or lesser effect (negative heterosis) for a quantitative or dichotomous trait than subjects homozygous for either allele.

I shall deal only with the heterosis concerned with the genetic balance-mechanisms underlying morphism (balanced polymorphism as defined by E. B. Ford). All morphisms found in nature must involve a selective balance between the morphs (R. A.

Heterosis: revisiting the magic
Trends in Genetics, 2007Heterosis results in the phenotypic superiority of a hybrid over its parents with respect to traits such as growth rate, reproductive success and yield. This hybrid vigor is determined by non-mutually exclusive mechanisms, including dominance complementation, overdominance and epistasis.

Efficiency of hybrid breeding could be greatly enhanced by reliable methods of prediction of F1 hybrids values or heterosis. Use of parents per se values through different approaches (including distance computation) should be of poor efficiency for species that exhibit high heterotic effects, such as Maize.

GENETICS
AbstractHeterosis refers to the superior performance of a hybrid over its parents. It is the basis for hybrid breeding particularly for maize and rice. Genetically it is due to interactions between alleles of quantitative trait loci (QTL) (dominance and epistasis).

Heterosis: Complementation by Mitochondria
Science, 1966Many (but not all) hybrids between two genetic pure lines show heterosis; that is the hybrids grow more rapidly or larger than the parental pure lines. The mechanism is not known. Two corn crosses were studied. In one hybrid known to exhibit heterosis, the mitochondria and an artificial 1:1 mixture of parent mitochondria showed heterosis with respect ...

Heterosis in chromosome behaviour
Proceedings of the Royal Society of London. Series B - Biological Sciences, 1955Most examples and measurements of heterosis are concerned with the more familiar features of the phenotype, with such characters as size and growth rate of the body or its outer parts. This account is concerned with less accessible, though not less important, parts of the phenotype, and describes heterosis as it is shown in certain aspects

The phenomenon of heterosis was first described by Darwin as having a positive effect on plant traits, as displayed by cross-fertilized over self-fertilized progenies in the vegetable kingdom. Shull and East's rediscovery of heterosis in 1906 paved the way for the introduction of the first maize hybrid varieties in the US market in early 1930.
