    Genome changes due to artificial selection in U.S. Holstein cattle
    (Springer Nature, 2019-02-11) Ma, Li; Sonstegard, Tad S.; Cole, John B.; VanTassell, Curtis P.; Wiggans, George R.; Crooker, Brian A.; Tan, Cheng; Prakapenka, Dzianis; Liu, George E.; Da, Yang
    The availability of a unique unselected Holstein line since 1964 provided a direct comparison between selected and unselected Holstein genomes whereas large Holstein samples provided unprecedented statistical power for identifying high-confidence SNP effects. Utilizing these unique resources, we aimed to identify genome changes affected by selection since 1964.

    Bos taurus–indicus hybridization correlates with intralocus sexual-conflict effects of PRDM9 on male and female fertility in Holstein cattle
    (Springer Nature, 2019-08-28) Seroussi, Eyal; Shirak, Andrey; Gershoni, Moran; Ezra, Ephraim; Santos, Daniel Jordan de Abreu; Ma, Li; Liu, George E.
    Crossover localization during meiotic recombination is mediated by the fast-evolving zinc-finger (ZnF) domain of gene PRDM9. To study its impact on dairy cattle performance, we compared its genetic variation between the relatively small Israeli (IL) Holsteins and the North American (US) Holsteins that count millions.
