Figure 2: Correlation between observed empirical genetic distance (Y) and simulated genetic distance (Y′). (a), the simple Mantel correlation between Y and Y′ for the IBR landscape is depicted across 1500 simulated generations (black line). Partial Mantel correlations controlling for the variance explained by the IBB hypothesis (light gray line) and IBD hypothesis (dark gray line) are also shown. (b), the simple Mantel correlation between Y and Y′ for the IBD landscape is depicted (dark gray line), with the partial correlations controlling for the variance explained by the IBR (black line) and IBB (light gray line) also shown. (c), the simple Mantel correlation between Y and Y′ for the IBB landscape is depicted (light gray line), with the partial correlations controlling for the variance explained by the IBR (black line) and IBB (dark gray line) also shown. In all panels, the gray vertical bar indicates the modern day (generation 1020), and the dotted lines indicate the standard deviation of the Mantel correlations across 10 Monte Carlo iterations.
