Selective Sweeps Under Dominance and Inbreeding [PDF]

open access: yesG3: Genes, Genomes, Genetics, 2020
A major research goal in evolutionary genetics is to uncover loci experiencing positive selection. One approach involves finding ‘selective sweeps’ patterns, which can either be ‘hard sweeps’ formed by de novo mutation, or ‘soft sweeps’ arising from ...

Candidate selective sweeps in US wheat populations [PDF]

open access: yesThe Plant Genome
Exploration of novel alleles from ex situ collection is still limited in modern plant breeding as these alleles exist in genetic backgrounds of landraces that are not adapted to modern production environments.

Recent Selective Sweeps in North American Drosophila melanogaster Show Signatures of Soft Sweeps [PDF]

open access: yesPLoS Genetics, 2015
Adaptation from standing genetic variation or recurrent de novo mutation in large populations should commonly generate soft rather than hard selective sweeps.

Localization of adaptive variants in human genomes using averaged one-dependence estimation [PDF]

open access: yesNature Communications, 2018
Selective sweeps are events in which beneficial mutations spread rapidly through a population. Here, Sugden et al. develop SWIF(r), a probabilistic classification framework for detecting and localizing selective sweeps, and apply it to genomic data from ...

Sweepstakes reproductive success via pervasive and recurrent selective sweeps [PDF]

open access: yeseLife, 2023
Highly fecund natural populations characterized by high early mortality abound, yet our knowledge about their recruitment dynamics is somewhat rudimentary.

Soft selective sweeps: Addressing new definitions, evaluating competing models, and interpreting empirical outliers [PDF]

open access: yesPLoS Genetics, 2022
The ability to accurately identify and quantify genetic signatures associated with soft selective sweeps based on patterns of nucleotide variation has remained controversial. We here provide counter viewpoints to recent publications in PLOS Genetics that

Selective sweeps on different pigmentation genes mediate convergent evolution of island melanism in two incipient bird species. [PDF]

open access: yesPLoS Genetics, 2022
Insular organisms often evolve predictable phenotypes, like flightlessness, extreme body sizes, or increased melanin deposition. The evolutionary forces and molecular targets mediating these patterns remain mostly unknown.

S/HIC: Robust Identification of Soft and Hard Sweeps Using Machine Learning

open access: yesPLoS Genetics, 2016
Detecting the targets of adaptive natural selection from whole genome sequencing data is a central problem for population genetics. However, to date most methods have shown sub-optimal performance under realistic demographic scenarios. Moreover, over the

Coalescent tree imbalance and a simple test for selective sweeps based on microsatellite variation. [PDF]

open access: yesPLoS Computational Biology, 2013
Selective sweeps are at the core of adaptive evolution. We study how the shape of coalescent trees is affected by recent selective sweeps. To do so we define a coarse-grained measure of tree topology. This measure has appealing analytical properties, its

Broad-scale variation in human genetic diversity levels is predicted by purifying selection on coding and non-coding elements

open access: yeseLife, 2022
Analyses of genetic variation in many taxa have established that neutral genetic diversity is shaped by natural selection at linked sites. Whether the mode of selection is primarily the fixation of strongly beneficial alleles (selective sweeps) or ...
