What can we learn by sampling genomes across clines?
Allele frequency clines reflect selection, whilst linkage disequilibria reflect patterns of gene flow and introgression. However, such patterns are noisy, because of sampling drift, patchy habitat, and the history of the cline; this makes it difficult to detect selection and gene flow by scanning across the genome. I review the inferences that can be made from genomic patterns of Fst, cline width, cline concordance, and introgression.
