Dual genetic mechanisms of heterosis: population structure and gene action. [PDF]

Front Plant Sci
IntroductionHeterosis refers to the superiority of a hybrid over its parents. Existing heterosis theory has not sufficiently addressed the contribution of inbreeding at both population level and the level of individual lines within populations.

Improvement in genetic evaluation of quantitative traits in sheep by enriching genetic model with dominance effects. [PDF]

Sci Rep
Although dominance effects play a major role in quantitative genetics, most studies on quantitative traits have often neglected dominance effects, assuming alleles act additively.

Genetic analysis of salinity tolerance in wheat (Triticum aestivum L.).

PLoS ONE, 2022
Understanding the genetics of salt tolerance is of utmost need to combat the rising prevalence of soil salinity through employing tolerant cultivars.

The integrative biology of genetic dominance [PDF]

Biological Reviews, 2021
ABSTRACTDominance is a basic property of inheritance systems describing the link between a diploid genotype at a single locus and the resulting phenotype. Models for the evolution of dominance have long been framed as an opposition between the irreconcilable views of Fisher in 1928 supporting the role of largely elusive dominance modifiers and Wright ...

Evaluation of a new additive-dominance genomic model and implications for quantitative genetics and genomic selection

Scientia Agricola, 2021
: The Fisher’s infinitesimal model is traditionally used in quantitative genetics and genomic selection, and it attributes most genetic variance to additive variance.

Dominance is common in mammals and is associated with trans-acting gene expression and alternative splicing

Genome Biology, 2023
Background Dominance and other non-additive genetic effects arise from the interaction between alleles, and historically these phenomena play a major role in quantitative genetics.

Mixed model methods for genomic prediction and variance component estimation of additive and dominance effects using SNP markers. [PDF]

PLoS ONE, 2014
We established a genomic model of quantitative trait with genomic additive and dominance relationships that parallels the traditional quantitative genetics model, which partitions a genotypic value as breeding value plus dominance deviation and ...

Evolution of dominance in gene expression pattern associated with phenotypic robustness

BMC Ecology and Evolution, 2021
Background Mendelian inheritance is a fundamental law of genetics. When we consider two genomes in a diploid cell, a heterozygote’s phenotype is dominated by a particular homozygote according to the law of dominance.

An F₂ Barley Population as a Tool for Teaching Mendelian Genetics

Plants, 2021
In the context of a general genetics course, mathematical descriptions of Mendelian inheritance and population genetics are sometimes discouraging and students often have serious misconceptions.

Selective Sweeps Under Dominance and Inbreeding

G3: Genes, Genomes, Genetics, 2020
A major research goal in evolutionary genetics is to uncover loci experiencing positive selection. One approach involves finding ‘selective sweeps’ patterns, which can either be ‘hard sweeps’ formed by de novo mutation, or ‘soft sweeps’ arising from ...
