Description

No insertion of P{ry+un2} at na.

(Nash, 2002.3.23)

Stated to be insertion of P{ry+un2} into na, hence naming of FBti0012424 as a transposon insertion. Note subsequent data (Nash, 2002.3.23, personal communication to FlyBase) states that Nash and Krishnan both believe there not to be an insertion at na in this allele.

      Reference

      Flies show a measurable resistance to halothane and characteristic saccadic walking behavior. Has a strong geotactic phenotype and the geotaxis index is close to that for nahar38. Response to enflurane and isoflurane is indistinguishable from wild type.

      Comments

      Alleles of na form a phenotypic series, going from strongest to weakest: nahar38 > nahar85 > naP890 > na1 > naPex1 > naPex2. Can revert to wild type under dysgenic conditions.
