Interplay between large low-recombining regions and pseudo-overdominance in a plant genome [PDF]

open access: goldNature Communications
To what extent overdominance might contribute to the maintenance of genetic diversity within genomes is still an ongoing research question. Pseudo-overdominance created by the complementation of deleterious alleles in heterozygotes has recently become a ...

Molecular Basis of Overdominance at a Flower Color Locus [PDF]

open access: goldG3: Genes, Genomes, Genetics, 2017
Single-gene overdominance is one of the major mechanisms proposed to explain heterosis (i.e., hybrid vigor), the phenomenon that hybrid offspring between two inbred lines or varieties show superior phenotypes to both parents.

Associative overdominance, heterozygosity and fitness [PDF]

open access: bronzeHeredity, 1998
Our aim in this study was to examine the power of associative overdominance in creating a correlation between individual heterozygosity and fitness and in maintaining genetic polymorphism at neutral loci. This was undertaken by simulating a diploid model with five chromosomes, each with 1000 loci that could have deleterious mutations linked to neutral ...

Comparative transcriptome analysis of inbred lines and contrasting hybrids reveals overdominance mediate early biomass vigor in hybrid cotton [PDF]

open access: goldBMC Genomics, 2020
Background Heterosis breeding is the most useful method for yield increase around the globe. Heterosis is an intriguing process to develop superior offspring to either parent in the desired character.

Maling bamboo (Yushania maling) overdominance alters forest structure and composition in Khangchendzonga landscape, Eastern Himalaya

open access: greenScientific Reports, 2022
The Khangchendzonga Landscape (KL), a part of ‘Himalayan Biodiversity Hotspot’, is known for its unique biodiversity assemblage. In recent years, the KL is experiencing threats to biodiversity due to the biological overdominance of native Maling bamboo ...

Behavioral cost & overdominance in Anopheles gambiae. [PDF]

open access: yesPLoS ONE, 2015
In response to the widespread use of control strategies such as Insecticide Treated Nets (ITN), Anopheles mosquitoes have evolved various resistance mechanisms.

A Least Squares Regression Model to Detect Quantitative Trait Loci with Polar Overdominance in a Cross of Outbred Breeds: Simulation [PDF]

open access: goldAsian-Australasian Journal of Animal Sciences, 2013
A least squares regression interval mapping model was derived to detect quantitative trait loci (QTL) with a unique mode of genomic imprinting, polar overdominance (POD), under a breed cross design model in outbred mammals. Tests to differentiate POD QTL

Six-gene model underlying heterosis for culm length and flowering date in sorghum (Sorghum bicolor (L.) Moench) [PDF]

open access: yesScientific Reports
Heterosis has been widely used to increase crop yield. Four genetic heterosis models have been proposed previously: dominance, overdominance, epistasis, and pseudo-overdominance models.

Associative overdominance caused by linked detrimental mutations [PDF]

open access: bronzeGenetical Research, 1971
SUMMARYAssociative overdominance due to linked detrimental mutations was investigated using the method of moment equations based on diffusion models. The expectation of the apparent selective value at the marker (neutral) locus has been evaluated. Assume two linked loci, at one of which the steady flux equilibrium is reached under constant mutational ...

Long‐Term Maintenance of Complex Chromosomal Inversion Polymorphism in Drosophila mediopunctata [PDF]

open access: yesEcology and Evolution
Natural selection is known to favor specific gene combinations, thereby shaping the evolution of recombination rates, often through epistatic interactions.
