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