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

open access: yesJournal 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.

Reduction of a metapopulation genetic model to an effective one island model [PDF]

open access: yes, 2018
We explore a model of metapopulation genetics which is based on a more ecologically motivated approach than is frequently used in population genetics. The size of the population is regulated by competition between individuals, rather than by artificially

Growth, competition and cooperation in spatial population genetics [PDF]

open access: yes, 2012
We study an individual based model describing competition in space between two different alleles. Although the model is similar in spirit to classic models of spatial population genetics such as the stepping stone model, here however space is continuous ...

Wright-fisher-like models with constant population size on average [PDF]

open access: yes, 2017
We first recall some basic facts from the theory of discrete-time Markov chains arising from two types neutral and non-neutral evolution models of population genetics with constant size.

The effect of recurrent mutations on genetic diversity in a large population of varying size [PDF]

open access: yes, 2016
Recurrent mutations are a common phenomenon in population genetics. They may be at the origin of the fixation of a new genotype, if they give a phenotypic advantage to the carriers of the new mutation.

Genetic draft, selective interference, and population genetics of rapid adaptation [PDF]

open access: yes, 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.

Population Growth Combined with Wide Offspring Distributions can Increase Fixation Rate and Reduce Genetic Diversity

open access: yesBulletin of Mathematical Biology, 2016
Genetic diversity grows with the population size in most neutral evolution models. Empirical evidence of large populations with limited diversity has been proposed to be due either to genetic bottlenecks or to selection. An alternative explanation is that the limited diversity is a result of rare reproduction events.
