The dominance model for heterosis explains culm length genetics in a hybrid sorghum variety [PDF]

Scientific Reports, 2021
Heterosis helps increase the biomass of many crops; however, while models for its mechanisms have been proposed, it is not yet fully understood. Here, we use a QTL analysis of the progeny of a high-biomass sorghum F1 hybrid to examine heterosis.

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

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.

Constraining models of dominance for nonsynonymous mutations in the human genome.

PLoS Genetics
Dominance is a fundamental parameter in genetics, determining the dynamics of natural selection on deleterious and beneficial mutations, the patterns of genetic variation in natural populations, and the severity of inbreeding depression in a population ...

Revisiting Dominance in Population Genetics [PDF]

Genome Biology and Evolution
Dominance refers to the effect of a heterozygous genotype relative to that of the two homozygous genotypes. The degree of dominance of mutations for fitness can have a profound impact on how deleterious and beneficial mutations change in frequency over ...

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.

Gene expression drives the evolution of dominance. [PDF]

Nature Communications, 2018
Dominance is a fundamental concept in molecular genetics and has implications for understanding patterns of genetic variation, evolution, and complex traits.

Genetics characteristics donor dominance short stem and large grain winter rye (Secale cereale L.)

Plant Varieties Studying and Protection, 2010
By means of directed selection during 39 generations of Rye plants bearing the highest expression of short stem in combination with largest size of grain, a donor of dominant short stem and recessive complimentary or epistatic large size grain has been ...

The Dominance Concept Inventory: A Tool for Assessing Undergraduate Student Alternative Conceptions about Dominance in Mendelian and Population Genetics

CBE - Life Sciences Education, 2014
Despite the impact of genetics on daily life, biology undergraduates understand some key genetics concepts poorly. One concept requiring attention is dominance, which many students understand as a fixed property of an allele or trait and regularly ...

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 ...
