Abundance of TE insertions in the chromosomes of D. melanogaster.

aNumber of identified TE insertions; All known TE insertions are in parenthesis.bFrequency estimates where obtained for non overlapping insertions having more than ten absence or presence fragments.cNumber of fixed TE insertions (>0.95 frequency).dFraction of fixed TE insertions nfixed/nfe.The total number of identified TE insertions (all) and the number of TE insertions present in the reference genome that have been identified by our approach (known) are shown. The numbers in brackets indicate the total number of TE insertions present in the reference genome. chr.: chromosome arm.
