Effect of the transgenic Drosophila-Sciara chimeric SXL proteins on male viability with and without endogenous normal Sxl allele.

The crosses to produce the males with a wild type endogenous Sxl allele are the following. For SXM, females yw; Sxm/MKRS,Sb & males w/Y; arm-GAL4[w+]; for SXS, females yw; Sxs/MKRS,Sb & males w/Y; arm-GAL4[w+]; for SX17, females yw; Sx17/MKRS,Sb & males w/Y; arm-GAL4[w+]; for SX64, females yw; Sx64/CyO,Cy & males w/Y; arm-GAL4[w+]; for SX35, females yw; Sx35/CyO,Cy & males w/Y; arm-GAL4[w+]; and for SX28, females yw; Sx28/CyO,Cy & males w/Y; arm-GAL4[w+]. Experimental males refer to those carrying the transgene and control to those carrying the balancer chromosome. The crosses to produce the males with an endogenous Sxl null allele are the following. The females in all crosses were ywSxlf1ct6/FM7; arm-Gal4,w+ and the males were: for SXM, yw/Y; Sxm/MKRS,Sb; for SXS, yw/Y; Sxs/MKRS,Sb; for SX17, yw/Y; Sx17/MKRS,Sb; for SX64, yw/Y; Sx64/CyO,Cy; for SX35, yw/Y; Sx35/CyO,Cy; and for SX28, yw/Y; Sx28/CyO,Cy. Experimental males refer to those carrying the endogenous Sxl null allele plus the transgene and control to those carrying the endogenous Sxl null allele plus the balancer chromosome.
