P-element insertion within exon 2 at nucleotide position 615 (coordinates from FBrf0058525).
Insertion of a P-element at map position +0.1.
1.1 kb P element insert at +0.1; Mitcheson, Simonelig, Williams and O'Hare (1993); the origin is at a SalI site close to the insertion of the P element used to clone the gene. Positive values are toward the centromere.
Mutant phenotype can be rescued by introduction of a wild type copy of su(f) by P element mediated transformation.
Simmons.
Excision of P-element by hybrid dysgenesis yields wild type revertants.
su(f)19, su(f)16-185, su(f)28, su(f)27, su(f)25 and su(f)3 exhibit the same pattern of complementation; fail to complement any su(f) allele. The allelic state of z has no effect on complementation behaviour.
