Transposase production and transpositional activation of the M-type element is limited to Dhel\P-element and Dmel\P-element, the D.bifasciata M-type elements have become immobile.
Two distinct P-element subfamilies, designated M-type and O-type, reside in the D.bifasciata genome. Results suggest that the O-type element of D.bifasciata has been received by horizontal transfer from an external source, as is previously suspected for the M-type family. Sequence analysis of the M-type elements demonstrates two independent intergenic transfer events must have occurred.
The genome of D.bifasciata harbours two distinct subfamilies of P-homologous sequences, designated M-type and O-type elements based on similarities to P-element sequences from other species. M-type and O-type elements have no common origin in the D.bifasciata lineage. M-type sequence is most closely related to the P-element from S.pallida, the origin of O-type elements cannot be deduced.

A full-length Dbif\P-element has been cloned and sequenced. The Dbif\P-element is 2935bp long, has 31bp inverted terminal repeats, and is flanked by 8bp duplications of the target site.
Transposable elements (TEs) from D.melanogaster are also found in species of the obscura group. Dbif\P-element shows close sequence similarity to the D.melanogaster homolog.
Transposase production and transpositional activation of the M-type element is limited to @Dhel\P-element@ and Dmel\@P-element@, the D.bifasciata M-type elements have become immobile.

A phylogenetic survey has identified four major P-element subfamilies in the saltans and willistoni species groups of Drosophila.
