Imprecise excision of the progenitor insertion, resulting in a 2225bp deletion extending from the original insertion site. The deletion encompasses the entire intergenic region between Drep-2 and Mad1 and the first 814bp of the Mad1 coding sequence (removing the first 272 of 730 codons of Mad1). The first transcription start site of Drep-2 is also removed.
2225 bp deletion resulting from the imprecise excision of P{EPgy2}Drep2EY12060, which removes the intergenic region between Drep2 and Mad1 and extends through codon 272 of Mad1. It also removes the first transcription start site of Drep2.
