Abstract excerpt

The period gene is a key regulator of biological rhythmicity in Drosophila melanogaster. The central part of the gene encodes a dipeptide Thr-Gly repeat that has been implicated in the evolution of both circadian and ultradian rhythms. We have previously observed that length variation in the repeat follows a latitudinal cline in Europe and North Africa, so we have sought to extend this observation to the southern...
