You're right. I should have chosen better phrasing - perhaps gene pool instead of population, and diluted (but that still seems awkward) rather than replaced.

  > Is an 11% genetic incursion a lot for ~ 150 generations? I am not sure either. However, we do have a lot of natural experiments (and lab experiments) to explore this. The 11% number comes from a clustering analysis. The user supplies k = number of ancestry groups, and the algorithm estimates proportion of genetics specific to each of k ancestry groups. So basically fancy k-means clustering. I don't know how robust it is and I would suspect a biased estimate. As for over time... also complex. But I would imagine the best models would use exponetial distributions or similar as their basis (i.e. initially fast decrease in percentage followed by a slower rate of loss until equilibrium is reached).
