On epistasis

COMPUTING AND INFORMATICS, 1995
Summary: We compare two previously introduced notions of epistasis and prove that they are essentially equivalent.

Genetic and Ecological Management of Pacific Salmon Fisheries for the 21st Century

Fisheries Management and Ecology, EarlyView.
ABSTRACT Based on ecological adaptation theory, tremendous effort is being spent on measures that are eliminating salmon hatcheries and fishing opportunities with the intention of protecting wild runs deemed to be of particular genetic importance to the survival of the species.

Epistatic interactions alter dynamics of multilocus gene-for-gene coevolution. [PDF]

PLoS ONE, 2007
Fitness costs associated with resistance or virulence genes are thought to play a key role in determining the dynamics of gene-for-gene (GFG) host-parasite coevolution. However, the nature of interactions between fitness effects of multiple resistance or

Generation mean analysis of the key earliness related traits in cowpea (Vigna unguiculata (L.) Walp)

Scientific African, 2022
The nature of gene action controlling agronomic traits enables plant breeders to execute a successful crop improvement programme. To elucidate the type of gene action governing the key earliness related traits in cowpea, seven populations of the six ...

Robustness and epistasis in mutation-selection models

, 2009
We investigate the fitness advantage associated with the robustness of a phenotype against deleterious mutations using deterministic mutation-selection models of quasispecies type equipped with a mesa shaped fitness landscape.

Genetic Parameters and Genome‐Wide Association Studies for Fertility and Reproduction Traits in U.S. Katahdin Sheep Based on the Single‐Step GBLUP Methodology

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Sheep production contributes to a secure and diverse food and fibre supply in the United States, with growing ethnic diversity strengthening demand. Katahdin is a composite hair‐type sheep breed developed in the United States that has become the most popular breed in many regions of the country and the first one to have genomic selection ...

Hamiltonian model for multidimensional epistasis [PDF]

, 2002
We propose and solve a Hamiltonian model for multidimensional epistastatic interactions between beneficial mutations. The model is able to give rise either to a phase transition between two equilibrium states, without any coexistence, or exhibits a state

Single-cell genomics reveals the genetic and molecular bases for escape from mutational epistasis in myeloid neoplasms.

Blood, 2020
Large-scale sequencing studies of hematologic malignancies have revealed notable epistasis among high-frequency mutations. One of the most striking examples of epistasis occurs for mutations in RNA splicing factors.

Constitutive and inducible oleoresin defenses share genetic architectures and mechanisms in Pinus taeda

New Phytologist, EarlyView.
Summary The oleoresin defense system of loblolly pine (Pinus taeda) protects trees from insects and pathogens and is an important source of renewable biofuels and chemicals, but the genetic basis of oleoresin production is poorly understood. We characterized the genetic architecture of oleoresin flow, resin canal number, stem wood terpene content, and ...
