Abstract.

The elements of the Bari 1, hobo, and pogo transposon families that are located in euchromatin, heterochromatin, and on the Y chromosome have been identified, and their stability has been assessed by Southern blot analysis. The fraction of heterochromatic elements appears to be distinctive of all transposon families tested, except for Bari 1. Evidence for instability of heterochromatic elements is described. The analysis of unstable elements in different Drosophila stocks suggests that the host genome contributes to the stability/instability of transposon families.

Key words:Drosophila melanogaster— Euchromatin — Heterochromatin — Intragenomic parasites — Transposable elements
