wupA << bk1 << fliH << bk2
Does not cause unconditional lethality in hybrid females when heterozygous with D.simulans chromosome.
Deficient embryos show an uninterpretable mutant midgut phenotype.
Homozygous embryos are very abnormal compared to wild-type.
Heterozygosity for this deletion has no effect on the mutant ovarian phenotype of ovoD2.
More than six-fold reduction in sex ratio and significant levels of female lethality is observed when in combination with Sxlf1. Female lethality is also reduced when in combination with da1 but restored when in combination with emcML.
'Sloppy' ventral cord.
