What doesn’t kill them makes them stronger: an association between elongation factor 1-α overdominance in the sea star Pisaster ochraceus and “sea star wasting disease” [PDF]
PeerJ, 2016 In recent years, a massive mortality event has killed millions of sea stars, of many different species, along the Pacific coast of North America. This disease event, known as ‘sea star wasting disease’ (SSWD), is linked to viral infection.

Emergence of a floral colour polymorphism by pollinator-mediated overdominance
Nature Communications, 2019 Examples of overdominance are usually explained by deleterious effects in homozygotes. Here, Kellenberger et al. describe a case of overdominance in the floral color of the Alpine orchid Gymnadenia rhellicani apparently maintained by pollinator ...

Partial Dominance, Overdominance and Epistasis as the Genetic Basis of Heterosis in Upland Cotton (Gossypium hirsutum L.). [PDF]
PLoS ONE, 2015 Determination of genetic basis of heterosis may promote hybrid production in Upland cotton (Gossypium hirsutum L.). This study was designed to explore the genetic mechanism of heterosis for yield and yield components in F2: 3 and F2: 4 populations ...

Genome-wide association testing in malaria studies in the presence of overdominance
Malaria Journal, 2023 Background In human genetics, heterozygote advantage (heterosis) has been detected in studies that focused on specific genes but not in genome-wide association studies (GWAS).

Resolving the Conflict Between Associative Overdominance and Background Selection [PDF]
Genetics, 2016 Abstract In small populations, genetic linkage between a polymorphic neutral locus and loci subject to selection, either against partially recessive mutations or in favor of heterozygotes, may result in an apparent selective advantage to heterozygotes at the neutral locus (associative overdominance) and a retardation of the rate of ...

Molecular mechanisms of heterosis under drought stress in maize hybrids Zhengdan7137 and Zhengdan7153 [PDF]
Frontiers in Plant ScienceMaize is one of the most successful crops in utilizing heterosis which significantly improves maize stresses resistance and yield. Drought is a destructive abiotic stress that significantly reduces crop yield, particularly in maize. Drought stress and re-

A Novel Rust Resistance Gene in Maize Showing Overdominance
Molecular Plant-Microbe Interactions, 1998 The Rp8 rust resistance locus of maize is unique in that only Rp8-A/Rp8-B heterozygotes provide resistance and homozygotes are susceptible. A third allele, Rp8-C, provides no resistance in homozygotes or heterozygous combinations.
