Phylogeny 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 % support
