Genotype by random environmental interactions gives an advantage to non-favored minor alleles

Scientific Reports, 2017
Fixation probability, the probability that the frequency of a newly arising mutation in a population will eventually reach unity, is a fundamental quantity in evolutionary genetics.

Simulating population genetics of pathogen vectors in changing landscapes: guidelines and application with Triatoma brasiliensis. [PDF]

PLoS Neglected Tropical Diseases, 2014
BACKGROUND:Understanding the mechanisms that influence the population dynamics and spatial genetic structure of the vectors of pathogens infecting humans is a central issue in tropical epidemiology.

Hybrid fitness effects modify fixation probabilities of introgressed alleles

G3: Genes, Genomes, Genetics, 2022
Hybridization is a common occurrence in natural populations, and introgression is a major source of genetic variation. Despite the evolutionary importance of adaptive introgression, classical population genetics theory does not take into account hybrid ...

RETRACTED: An innovative panel containing a set of insertion/deletion loci for individual identification and its forensic efficiency evaluations in Chinese Hui ethnic minority

Molecular Genetics & Genomic Medicine, 2020
Background Individual identification is one of the most important tasks in the field of forensic genetics. Insertion/Deletion (InDel) polymorphism marker has been a promising marker for individual identification. However, a part of InDel loci in commonly

Anthropogenic and natural fragmentations shape the spatial distribution and genetic diversity of roe deer in the marginal area of its geographic range

Ecological Indicators, 2023
Habitat destruction and fragmentation are major factors in the destruction of genetic diversity and affect the movement behavior of the Roe deer population in the remaining habitats.

Genetic Diversity and Structure of Calophyllum brasiliense Along the Santa Catarina Coast

Floresta e Ambiente, 2019
Population genetics studies can provide knowledge in support of conservation efforts for plant populations. We studied the genetic diversity and structure in nine populations of Calophyllum brasiliense from Santa Catarina state, Brazil, aiming to ...

Development and characterization of microsatellite markers for Antennaria corymbosa (Asteraceae) and close relatives

Applications in Plant Sciences, 2019
Premise The genus Antennaria has a complex evolutionary history due to dioecism, excessive polyploidy, and the evolution of polyploid agamic complexes. We developed microsatellite markers from A.

A new method for ecologists to estimate heterozygote excess and deficit for multi‐locus gene families

Ecology and Evolution
The fixation index, FIS, has been a staple measure to detect selection, or departures from random mating in populations. However, current Next Generation Sequencing (NGS) cannot easily estimate FIS, in multi‐locus gene families that contain multiple loci

Numerical Solutions for Fractional Fixation Times in Evolutionary Models

Axioms
The fixation time of alleles is a fundamental concept in population genetics, traditionally studied using the Wright–Fisher model and classical coalescent theory.

Stronger selection can slow down evolution driven by recombination on a smooth fitness landscape. [PDF]

PLoS ONE, 2017
Stronger selection implies faster evolution-that is, the greater the force, the faster the change. This apparently self-evident proposition, however, is derived under the assumption that genetic variation within a population is primarily supplied by ...
