amorphic allele
Insertion of TI{CRISPaint.T2A-GAL4} sequence into bc10. The insertion is in antisense orientation (T2A-GAL4 sequence within the inserted sequence cassette is in the opposite orientation to transcription of bc10), thus no GAL4 expression is seen.
A 6894 bp insertion into the bc10 gene inserted in the reverse orientation relative to bc10.
