Maximum genetic contribution of native American dogs under the isolation-admixture model. Lines represent the 95 percent limit under different assumptions about effective population size (varying across the x-axis) and generation time. The results assuming a two year generation time are shown with a solid curve and the results assuming a three year generation time with a dashed curve.
