Twenty X chromosomes isolated from a natural population of Drosophila melanogaster were surveyed using in situ hybridization to determine the number and cytogenetic location of three families of transposable elements: copia, 412 and 297. We found no sites of insertions in high frequency; in fact, frequencies of specific sites for all three elements were so low that each insertion could be interpreted as being unique. This suggests that rates of transposition and deletion for these elements are very high. Our data also show a higher than expected rate of the co-occurrence of different elements at the same site on the same chromosome.
