Detailed Description
Statement
Reference

2 copies of schb.PP cause male lethality.

Male-specific lethality due to inappropriate activation of Sxl. Can rescue the female lethality of hhb.PP.

Causes male specific lethality and activates ectopic Sxl expression in the anterior of male embryos (Parkhurst et al., Cell 63: 1179--1191.)

Female viability is unaffected. Head morphology of males is defective.

Additional Comments
Genetic Interactions
Statement
Reference

Expression of hhb.PP can rescue male lethality caused by schb.PP. Deletion of the bHLH and orange domains of h render it unable to rescue male lethality, the WRPW domain is not required for rescue. Expression of E(spl)hb.PD cannot rescue male lethality caused by schb.PP.

Ectopic h expression (hhb.PP) rescues schb.PP male lethality. Extra copies of da+ do not effect male lethality of schb.PP.

schb.PP/SxlM1 male embryos are fully viable.
