Table 1 Interaction between population size and persistence time

From: Widespread horizontal genomic exchange does not erode species barriers among sympatric ducks

  Census size Nc Effective size Ne Persistence time (mean)
    p = 0.5 p = 0.1
Anasplatyrhynchos 19,000,000 1,900,000 5,267,919 2,470,631

  1. Population sizes Nc and Ne and mean persistence times in generations of the most balanced (p = 0.5; maximum frequency) and a rare (p = 0.1) SNP in each duck species. A ratio of 0.1 for Ne/Nc was assumed (see methods for more info).
