Seedling salt tolerance in tomato [PDF]

, 2011
Soils with higher concentrations of salt are becoming more and more a constraint for many crops to obtain high yields. Wild tomato species, adapted to adverse environments, are a potential reservoir for genes underlying quantitative trait loci (QTL ...

Revisiting Dominance in Population Genetics

Genome Biology and Evolution
Abstract 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 time as well as on the patterns of linked neutral genetic variation ...

Selection responses of means and inbreeding depression for female fecundity in Drosophila melanogaster suggest contributions from intermediate-frequency alleles to quantitative trait variation [PDF]

, 2007
The extent to which quantitative trait variability is caused by rare alleles maintained by mutation, versus intermediate-frequency alleles maintained by balancing selection, is an unsolved problem of evolutionary genetics.

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 ...

Allele interaction--single locus genetics meets regulatory biology. [PDF]

PLoS ONE, 2010
BACKGROUND: Since the dawn of genetics, additive and dominant gene action in diploids have been defined by comparison of heterozygote and homozygote phenotypes.

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 ...

Quantitative genetics theory for genomic selection and efficiency of breeding value prediction in open-pollinated populations

Scientia Agricola, 2016
To date, the quantitative genetics theory for genomic selection has focused mainly on the relationship between marker and additive variances assuming one marker and one quantitative trait locus (QTL).

20 questions on Adaptive Dynamics [PDF]

, 2005
Adaptive Dynamics is an approach to studying evolutionary change when fitness is density or frequency dependent. Modern papers identifying themselves as using this approach first appeared in the 1990s, and have greatly increased up to the present ...

Genomic selection models for directional dominance: an example for litter size in pigs

Genetics Selection Evolution, 2018
Background The quantitative genetics theory argues that inbreeding depression and heterosis are founded on the existence of directional dominance.

Detection of quantitative trait loci for locomotion and osteochondrosis-related traits in Large White x Meishan pigs. [PDF]

, 2003
Data from the F2 generation of a Large White (LW) 5 Meishan (MS) crossbred population were analysed to detect quantitative trait loci (QTL) for leg and gait scores, osteochondrosis and physis scores.
