Spatial and temporal variation in allele frequencies.

<p>(A) Genomic distribution of clinal (black line) and seasonal SNPs (red line) per megabase per common polymorphism used in this study (<a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.1004775#pgen.1004775.s008" target="_blank">Table S1</a>). (B). Enrichment (log₂ odds ratio) of seasonal SNPs with spatial <i>F_ST</i> greater than or equal to value on <i>x</i>-axis relative to control SNPs. (C) Enrichment (log₂ odds ratio) of seasonal SNPs with –log₁₀(spatial q-value) greater than or equal to value on <i>x</i>-axis relative to control SNPs. (D) Absolute difference between average spring (blue) and fall (red) frequencies in the Pennsylvanian population and frequency estimates along the cline. Confidence bands represent 95% confidence intervals based on blocked bootstrap resampling.
