Reintegration of the 19.3 kb fragment removed in Abd-Biab-5.6.CI carrying an approximately 2.9 kb internal deletion spanning Drosophila genome project release 5 coordinates 3R:12716494-12719281 .
In flies homozygous for Abd-Biab-6.1, abdominal segment A6 seems to be completely transformed into A5. This can be clearly seen on the adult cuticle where the sixth sternite takes on the shape and bristle pattern characteristic of A5.
