Genetic Signatures of Evolutionary Rescue by a Selective Sweep. [PDF]
Genetics, 2020 AbstractOne of the most useful models in population genetics is that of a selective sweep and the consequent hitch-hiking of linked neutral alleles. While variations on this model typically assume constant population size, many instances of strong selection and rapid adaptation in nature may co-occur with complex demography.

An Eco-Evolutionary approach of Adaptation and Recombination in a large population of varying size [PDF]
, 2014 We identify the genetic signature of a selective sweep in a population described by a birth-and-death process with density dependent competition. We study the limit behaviour for large K, where K scales the population size.

Genealogies of two linked neutral loci after a selective sweep in a large population of stochastically varying size [PDF]
, 2016 We study the impact of a hard selective sweep on the genealogy of partially linked neutral loci in the vicinity of the positively selected allele. We consider a sexual population of stochastically varying size and, focusing on two neighboring loci ...

A survey of methods and tools to detect recent and strong positive selection
Journal of Biological Research - Thessaloniki, 2017 Positive selection occurs when an allele is favored by natural selection. The frequency of the favored allele increases in the population and due to genetic hitchhiking the neighboring linked variation diminishes, creating so-called selective sweeps ...

Selective sweep in the Flotillin-2 region of European Drosophila melanogaster. [PDF]
PLoS ONE, 2013 Localizing genes that are subject to recent positive selection is a major goal of evolutionary biology. In the model organism Drosophila melanogaster many attempts have been made in recent years to identify such genes by conducting so-called genome scans

On Detecting Selective Sweeps Using Single Genomes [PDF]
Frontiers in Genetics, 2011 Identifying the genetic basis of human adaptation has remained a central focal point of modern population genetics. One major area of interest has been the use of polymorphism data to detect so-called "footprints" of selective sweeps - patterns produced as a beneficial mutation arises and rapidly fixes in the population.

A selective sweep of >8 Mb on chromosome 26 in the Boxer genome
BMC Genomics, 2011 Background Modern dog breeds display traits that are either breed-specific or shared by a few breeds as a result of genetic bottlenecks during the breed creation process and artificial selection for breed standards.

Soft selective sweeps in complex demographic scenarios [PDF]
Genetics, 2014 Recent studies have shown that adaptation from de novo mutation often produces so-called soft selective sweeps, where adaptive mutations of independent mutational origin sweep through the population at the same time. Population genetic theory predicts that soft sweeps should be likely if the product of the population size and the mutation rate towards ...
