Quantitative traits [PDF]

open access: yes, 2013
Quantitative traits are phenotypic traits that are determined, jointly with the environment, by many genes of small effect. Most of the directly observable individual characteristics are quantitative traits.

Quantitative genetics of disease traits [PDF]

open access: yesJournal of Animal Breeding and Genetics, 2015
John James authored two key papers on the theory of risk to relatives for binary disease traits and the relationship between parameters on the observed binary scale and an unobserved scale of liability (James Annals of Human Genetics, 1971; 35: 47; Reich,

Genetic Divergence of Lineage-Specific Tandemly Duplicated Gene Clusters in Four Diploid Potato Genotypes

open access: yesFrontiers in Plant Science, 2022
Potato (Solanum tuberosum L.) is the most important non-grain food crop. Tandem duplication significantly contributes to genome evolution. The objectives of this study were to (i) identify tandemly duplicated genes and compare their genomic distributions

Association analysis of some morphological traits of durum wheat (Triticum turgidum var. Durum Desf) in rainfed and supplementary irrigation conditions using SSR molecular marker [PDF]

open access: yesبیوتکنولوژی و بیوشیمی غلات, 2022
Introduction: Durum wheat is one of the most important crops in the world. Various environmental stresses such as drought stress can affect grain yield. Drought stress is one of the most important and common causes of wheat yield decline in most parts of

Polygenic adaptation after a sudden change in environment

open access: yeseLife, 2022
Polygenic adaptation is thought to be ubiquitous, yet remains poorly understood. Here, we model this process analytically, in the plausible setting of a highly polygenic, quantitative trait that experiences a sudden shift in the fitness optimum.

Rapid Evolutionary Adaptation in Response to Selection on Quantitative Traits

open access: yesLife, 2021
Evolutionary adaptation after sudden environmental changes can occur very rapidly. The mechanisms facilitating rapid adaptation range from strong positive directional selection leading to large shifts in the allele frequencies at a few loci (selective ...

Prospects and Potential Uses of Genomic Prediction of Key Performance Traits in Tetraploid Potato

open access: yesFrontiers in Plant Science, 2018
Genomic prediction is a routine tool in breeding programs of most major animal and plant species. However, its usefulness for potato breeding has not yet been evaluated in detail.
