Fig. 2From: Natural selection in a population of Drosophila melanogaster explained by changes in gene expression caused by sequence variation in core promoter regionsPhylogeny of different alleles of CPRs for CHKov1 and CG33506 found in the natural population. Neighbor-joining trees for different alleles (a-c and d-f) of CPR sequences are shown for CHKov1 (a) and CG33506 (b) found in a natural population of D. melanogaster. D. simulans was used as an outgroup (o). Bootstrap values are shown for nodes with > 60 % supportBack to article page
