Interplay between pleiotropy and secondary selection determines rise and fall of mutators in stress response. [PDF]

PLoS Computational Biology, 2010
Mutators are clones whose mutation rate is about two to three orders of magnitude higher than the rate of wild-type clones and their roles in adaptive evolution of asexual populations have been controversial.

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

Europhys. Lett. 122, 18001 (2018), 2017
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 imposing a fixed population size.

The propagation of a cultural or biological trait by neutral genetic drift in a subdivided population [PDF]

Theoretical Population Biology (2007) 71 454, 2006
We study fixation probabilities and times as a consequence of neutral genetic drift in subdivided populations, motivated by a model of the cultural evolutionary process of language change that is described by the same mathematics as the biological process.

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 ...

Health influenced by genetics: A first comprehensive analysis of breast cancer high and moderate penetrance susceptibility genes in the Tunisian population

PLoS ONE, 2022
Significant advances have been made to understand the genetic basis of breast cancer. High, moderate and low penetrance variants have been identified with inter-ethnic variability in mutation frequency and spectrum. Genome wide association studies (GWAS)

Explaining spatial heterogeneity in population dynamics and genetics from spatial variation in resources for a large herbivore. [PDF]

PLoS ONE, 2012
Fine-scale spatial variation in genetic relatedness and inbreeding occur across continuous distributions of several populations of vertebrates; however, the basis of observed variation is often left untested.

Limiting Genotype Frequencies of Y-Linked Genes with a Mutant Allele in a Two-Sex Population

Mathematics, 2021
A two-type two-sex branching process is considered to model the evolution of the number of carriers of an allele and its mutations of a Y-linked gene. The limiting growth rates of the different types of couples and males (depending on the allele, mutated

Interplay between extreme drift and selection intensities favors the fixation of beneficial mutations in selfing maize populations [PDF]

Genetics, 2020
Abstract Population and quantitative genetic models provide useful approximations to predict long-term selection responses sustaining phenotypic shifts, and underlying multilocus adaptive dynamics. Valid across a broad range of parameters, their use for understanding the adaptive dynamics of small selfing populations undergoing strong ...
