Fixation in Conditional Branching Process Models in Population Genetics [PDF]

Journal of Applied Probability, 2007
An alternative version of the necessary and sufficient condition for almost sure fixation in the conditional branching process model is derived. This formulation provides an insight into why the examples considered in Buckley and Seneta (1983) all have the same condition for fixation.

Fixation probabilities in network structured meta-populations

Scientific Reports, 2021
The effect of population structure on evolutionary dynamics is a long-lasting research topic in evolutionary ecology and population genetics. Evolutionary graph theory is a popular approach to this problem, where individuals are located on the nodes of a

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 ...

A theory of evolutionary dynamics on any complex population structure reveals stem cell niche architecture as a spatial suppressor of selection

Nature Communications
How the spatial arrangement of a population shapes its evolutionary dynamics has been of long-standing interest in population genetics. Most previous studies assume a small number of demes or symmetrical structures that, most often, act as well-mixed ...

Spatial population genetics with fluid flow [PDF]

Reports on progress in physics. Physical Society, 2021
The growth and evolution of microbial populations is often subjected to advection by fluid flows in spatially extended environments, with immediate consequences for questions of spatial population genetics in marine ecology, planktonic diversity and ...

Invasion and effective size of graph-structured populations. [PDF]

PLoS Computational Biology, 2018
Population structure can strongly affect evolutionary dynamics. The most general way to describe population structures are graphs. An important observable on evolutionary graphs is the probability that a novel mutation spreads through the entire ...

FSTest: an efficient tool for cross-population fixation index estimation on variant call format files

bioRxiv, 2023
Fixation index ( F _st) statistics provide critical insights into evolutionary processes affecting the structure of genetic variation within and among populations.

Population Genetics with Fluctuating Population Sizes [PDF]

Journal of statistical physics, 2017
Standard neutral population genetics theory with a strictly fixed population size has important limitations. An alternative model that allows independently fluctuating population sizes and reproduces the standard neutral evolution is reviewed.
