"We analyzed the genomic P elements of 57 wild-derived Drosophila melanogaster isofemale lines from Africa, Australia and Asia. A11 carried many P sequences per genome, and the full-size P and the internally deleted KP elements were very common or predominant in the populations. The genomic content of full-size P and KP elements does not correlate well with the P transposition-inducing and -repressing abilities of a line. Our results show that a large majority of type I repressor elements are full-size P elements, and almost all type II repressor elements are KP elements in the natural populations of D. melanogaster from these parts of the world.
