The Scale of Population Structure in Arabidopsis thaliana

Figure 6

Pairwise distribution of non-shared alleles as a function of geographic distance and continent.

Boxes show median, 25th and 75th percentile; whiskers show 9th and 91st percentile. Shading shows relative (within panel) number of observations per bin. Blue line is curve of the form y = mx+b that is best fit to the binned data. Red line is model of exponential decay of the form y = K-Cexp(−λ*x) that is best fit to the binned data. (A,B) use 150 km bins. (C,D) use 10 km bins. (E,F) use 1/2 km bins. Data in (A,E) would not converge on an exponential curve.
