Gene conversion due to excision of P{bluetail}Abd-Bblt (carried over Fab-71 to avoid conversion with the homologue) using Abd-BFab7-2.tHa.gypsy\su(Hw)BR-340 as an ectopic template, has produced a chromosome containing the Fab-72 deletion with gypsy\su(Hw)BR340 inserted 140bp from it.
In Abd-BFab7-2.gypsy\su(Hw)BR-340 homozygous adult males, segment (A) 5 / parasegment (PS) 10 identity is normal, but A6/PS11 is transformed into A5/PS10. In Abd-BFab7-2.gypsy\su(Hw)BR-340 heterozygous males the sixth sternite and tergite are normal in size; i.e.- the presence of gypsy\su(Hw)BR340 completely suppress the transformation phenotype due to Abd-BFab7-2/+.
Abd-BFab7-2.gypsy\su(Hw)BR-340 has adult abdominal segment 5 | ectopic phenotype, non-suppressible by mod(mdg4)ul
Abd-BFab7-2.gypsy\su(Hw)BR-340 has adult abdominal segment 6 phenotype, non-suppressible by mod(mdg4)ul
In a su(Hw)V/su(Hw)7 background, the adbdominal phenotype of Abd-BFab7-2.gypsy\su(Hw)BR-340/+ males reverts to that seen in Fab-72 flies. The phenotype seen in Abd-BFab7-2.gypsy\su(Hw)BR-340 homozygous adult males is unaffected by mod(mdg4)ul/mod(mdg4)ul.
