Cytology
Description

Imprecise excision of the progenitor insertion, resulting in a deletion that removes the entire spn-B open reading frame and 9bp of the 3'UTR. 633bp of the original P{GSV6} insertion remain.

Comment:

Deletion resulting from the imprecise excision of P{GSV6}spn-BGS13042. The deletion removes the entire spn-B open reading frame as well as 9 bases from the 3' UTR. 633 bp of the P element remain at the site of the excision.

      Statement
      Reference

      Eggs laid by spn-BBU/spn-BΔ37C females display a range of ventralisation phenotypes, ranging from fusion at the base of the dorsal appendages through to complete lack of the appendages.

      Statement
      Reference

      The ventralisation phenotype seen in eggs laid by spn-BBU/spn-BΔ37C females is suppressed if the females are also mutant for LnkCR642/Lnkf05062.
