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.

POPULATION GENETICS, PLEIOTROPY, AND THE PREFERENTIAL FIXATION OF MUTATIONS DURING ADAPTIVE EVOLUTION [PDF]
Evolution, 2010 Ongoing debate centers on whether certain types of mutations are fixed preferentially during adaptive evolution. Although there has been much discussion, no quantitative framework currently exists to test for these biases. Here, we describe a method for distinguishing between the two processes that likely account for biased rates of substitution ...

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

Fixation Time for Competing Beneficial Mutations and Their Genomic Footprint. [PDF]
Biology (Basel)Simple Summary Knowing how fast natural selection can act on changes in the environment is fundamental for understanding evolution. The time it takes for a beneficial mutation to spread through a natural population has been investigated thoroughly in the

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 ...

Nature CommunicationsHow 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 ...
