    A novel expectation-maximization approach to infer general diploid selection from time-series genetic data. by Adam G Fine, Matthias Steinrücken

    Published 2025-07-01
    “…Using extensive simulation studies, we find that our method accurately and efficiently estimates selection coefficients for different modes of diploid selection across a wide range of scenarios; however, power to classify the mode of selection is low unless selection is very strong. We apply our method to ancient DNA samples from Great Britain in the last 4,450 years and detect evidence for selection in six genomic regions, including the well-characterized LCT locus. …”
