Selective sweeps in SARS-CoV-2 variant competition

open access: yesProceedings of the National Academy of Sciences, 2022
The main mathematical result in this paper is that change of variables in the ordinary differential equation (ODE) for the competition of two infections in a Susceptible–Infected–Removed (SIR) model shows that the fraction of cases due to the new variant satisfies the logistic differential equation, which models selective sweeps.

Modelling chemical reactions using semiconductor quantum dots [PDF]

open access: yes, 2007
We propose using semiconductor quantum dots for a simulation of chemical reactions as electrons are redistributed among such artificial atoms. We show that it is possible to achieve various reaction regimes and obtain different reaction products by ...

A novel locus on chromosome 1 underlies the evolution of a melanic plumage polymorphism in a wild songbird [PDF]

open access: yesRoyal Society Open Science, 2017
Understanding the mechanisms responsible for phenotypic diversification within and among species ultimately rests with linking naturally occurring mutations to functionally and ecologically significant traits.

Genetic drift at expanding frontiers promotes gene segregation [PDF]

open access: yes, 2007
Competition between random genetic drift and natural selection plays a central role in evolution: Whereas non-beneficial mutations often prevail in small populations by chance, mutations that sweep through large populations typically confer a selective ...

Fixation probability for competing selective sweeps

open access: yesElectronic Journal of Probability, 2012
We consider a biological population in which a beneficial mutation is undergoing a selective sweep when a second beneficial mutation arises at a linked locus and we investigate the probability that both mutations will eventually fix in the population.

An accurate model for genetic hitch-hiking

open access: yes, 2007
We suggest a simple deterministic approximation for the growth of the favoured-allele frequency during a selective sweep. Using this approximation we introduce an accurate model for genetic hitch-hiking.

IAMBEE : a web-service for the identification of adaptive pathways from parallel evolved clonal populations [PDF]

open access: yes, 2019
IAMBEE is a web server designed for the Identification of Adaptive Mutations in Bacterial Evolution Experiments (IAMBEE). Input data consist of genotype information obtained from independently evolved clonal populations or strains that show the same ...

Effects of Linked Selective Sweeps on Demographic Inference and Model Selection [PDF]

open access: yesGenetics, 2016
Abstract The availability of large-scale population genomic sequence data has resulted in an explosion in efforts to infer the demographic histories of natural populations across a broad range of organisms. As demographic events alter coalescent genealogies, they leave detectable signatures in patterns of genetic variation within and ...

Evidence for sweep signatures in antibiotic-resistant strains in three species of bacteria [PDF]

open access: yesPeerJ
Over the last decades antibiotic resistance has evolved and spread in many different bacterial species. From an evolutionary perspective, drug resistance is an adaptation to a new environment.

The clarifying role of time series data in the population genetics of HIV.

open access: yesPLoS Genetics, 2021
HIV can evolve remarkably quickly in response to antiretroviral therapies and the immune system. This evolution stymies treatment effectiveness and prevents the development of an HIV vaccine.
