    Effects of multiple sources of genetic drift on pathogen variation within hosts. by David A Kennedy, Greg Dwyer

    Published 2018-03-01
    “…Moreover, previous studies have used genetic data to infer the strength of genetic drift, whereas we test whether the genetic drift imposed by pathogen population processes can be used to explain genetic data. …”

    High functional diversity in Mycobacterium tuberculosis driven by genetic drift and human demography. by Ruth Hershberg, Mikhail Lipatov, Peter M Small, Hadar Sheffer, Stefan Niemann, Susanne Homolka, Jared C Roach, Kristin Kremer, Dmitri A Petrov, Marcus W Feldman, Sebastien Gagneux

    Published 2008-12-01
    “…We further demonstrate that these organisms are under extremely reduced purifying selection and that, as a result of increased genetic drift, much of this genetic diversity is likely to have functional consequences. …”

    Harvest and decimation affect genetic drift and the effective population size in wild reindeer by Thomas Kvalnes, Øystein Flagstad, Jørn Våge, Olav Strand, Hildegunn Viljugrein, Bernt‐Erik Sæther

    Published 2024-04-01
    “…The effective population size (Ne) is a fundamental parameter for describing such changes as it determines the amount of genetic drift in a population. Here, we estimate Ne of a harvested wild reindeer population in Norway. …”

    On theoretical models of gene expression evolution with random genetic drift and natural selection. by Osamu Ogasawara, Kousaku Okubo

    Published 2009-11-01
    “…The relative contributions of natural selection and random genetic drift are a major source of debate in the study of gene expression evolution, which is hypothesized to serve as a bridge from molecular to phenotypic evolution. …”

    Recent genetic drift in the co-diversified gut bacterial symbionts of laboratory mice by Daniel D. Sprockett, Brian A. Dillard, Abigail A. Landers, Jon G. Sanders, Andrew H. Moeller

    Published 2025-03-01
    “…Compared to closely related wild-mouse gut microbiota (WGM) strains, co-diversified LGM strains displayed significantly faster genome-wide rates of nonsynonymous substitutions, indicating elevated genetic drift—a difference that was absent in non-co-diversified symbiont clades. …”

    The Weight of Genetic Drift: A Pedigree-Based Evaluation of the Breton Horse Population in Brazil by Bruno B. Medeiros, Kate M. C. Barcelos, Millena Oliveira Andrade, Michele Cristina da Paz Carvalho, Victoria Rocha Miranda, Kalebe de Oliveira Maia, Susana Reinhardt, Laura Patterson Rosa

    Published 2024-01-01
    “…The RP inbreeding levels have stabilized, although they are still significantly rising by generation (t), and the Nfe/Ng ratio strongly suggests genetic drift. Pedigree-based analysis demonstrates that only five stallions have sired 52.83% of the RP individuals, which along with the Nae value of 36.73 implies that the observed inbreeding can be arising from patrilines. …”

    Neutral genetic drift can alter promiscuous protein functions, potentially aiding functional evolution by Lu Zhongyi, Romero Philip A, Bloom Jesse D, Arnold Frances H

    Published 2007-06-01
    “…</p> <p>Conclusion</p> <p>Our work suggests that initially neutral genetic drift can lead to substantial changes in protein functions that are not currently under selection, in effect poising the proteins to more readily undergo functional evolution should selection favor new functions in the future.…”
