Subject: Sxl allele on Binsc, oc1 ptg1 Personal communication from: Mel Green, U.C. Davis To: Bloomington Drosophila Stock Center Subject: Sxl allele on Binsc, oc1 ptg1 Dated: 15 Feb 2005 The Binsc variant marked with oc1 and ptg1, Binscop (FBba0000392), is viable when hemizygous and lethal when homozygous. Mel Green did a complementation test with this chromosome and a Sxl allele (he did not specify the allele) and found failure to complement, indicating that Binscop carries a Sxl allele. This is almost certainly Sxlf1, introduced via the In(1)dl-49 component of Binsc.
