Population Structure and Genomic Distributions of Various Statistics

<div><p>(A) Results from Structure under different assumptions about the number of clusters (<i>K</i> = 2,…, 8). Each individual is represented by a line, which is partitioned into <i>K</i> colored segments according to the individual's estimated membership fractions in each of the <i>K</i> clusters. The assignment of each individual is the average across the genome.</p> <p>(B) Results from Structure across Chromosome 1 for <i>K</i> = 3. Each chromosomal segment is colored according to the cluster in which it had the highest probability of membership.</p> <p>(C) A plot showing those fragments that appear to be monophyletic with respect to each of the three clusters identified by Structure.</p> <p>(D) <i>F_ST</i> with respect to the same three clusters (blue solid line) and the lower 95th percentile of <i>F_ST</i> obtained through 1,000 random permutations of the accessions (red dotted line).</p> <p>(E) θ̂<i>_P</i> within each of the three clusters. </p> <p>(F) Tajima's <i>D</i> statistic within each of the three clusters.</p> <p>(G) Results from Structure across Chromosome 1 for <i>K</i> = 8.</p> <p>(H) A plot showing those fragments that appear to be monophyletic with respect to each of these eight clusters.</p> <p>(I) <i>F_ST</i> with respect to these eight clusters.</p>
