An example output of the θπ track visualization in UCSC genome browser. An example output of sliding window analysis of Tajima's π of a Portuguese D. melanogaster population on chromosome X: 2044135-2053016 displayed in the linked UCSC genome browser. The pronounced drop in variability around the gene crm has been previously described, suggesting that at least one favorable mutation has recently spread in cosmopolitan D. melanogaster populations [12].
