Formal properties of the probability of fixation: identities, inequalities and approximations [PDF]
Theoretical Population Biology, 99: 98-113 (2015), 2013 The formula for the probability of fixation of a new mutation is widely used in theoretical population genetics and molecular evolution. Here we derive a series of identities, inequalities and approximations for the exact probability of fixation of a new mutation under the Moran process (equivalent results hold for the approximate probability of ...

An experimental test on the probability of extinction of new genetic variants [PDF]
, 2013 In 1927, J.B.S. Haldane reasoned that the probability of fixation of new beneficial alleles is twice their fitness effect. This result, later generalized by M. Kimura, has since become the cornerstone of modern population genetics.

Genetic draft, selective interference, and population genetics of rapid adaptation [PDF]
, 2013 To learn about the past from a sample of genomic sequences, one needs to understand how evolutionary processes shape genetic diversity. Most population genetic inference is based on frameworks assuming adaptive evolution is rare.

Hitchhiking to speciation. [PDF]
PLoS Biology, 2013 The modern evolutionary synthesis codified the idea that species exist as distinct entities because intrinsic reproductive barriers prevent them from merging together. Understanding the origin of species therefore requires understanding the evolution and

Technologically modified genes in natural populations [PDF]
, 1993 Current theories of evolutionary and ecological genetics cannot be used for general statements on risk assessment of gene technology. In a simplifying model, the genes which are transferred from artificial populations are treated like mutations in the ...

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 ...

Fixation properties of subdivided populations with balancing selection [PDF]
Phys. Rev. E 91, 032130 (2015), 2014 In subdivided populations, migration acts together with selection and genetic drift and determines their evolution. Building up on a recently proposed method, which hinges on the emergence of a time scale separation between local and global dynamics, we study the fixation properties of subdivided populations in the presence of balancing selection.

Fixation and Polarization in a Three-Species Opinion Dynamics Model [PDF]
, 2011 Motivated by the dynamics of cultural change and diversity, we generalize the three-species constrained voter model on a complete graph introduced in [J. Phys. A 37, 8479 (2004)].
