Females deficient for ovarian sax function produce two classes of abnormal eggs. The majority class has abnormal dorsal appendages, the minority class shows reduced egg length as well as abnormal dorsal appendages.

Rescues larval/pupal lethality of sax1rv1. A low level of rescue is seen even without heat shock.
Used to generate flies with loss of function sax in the ovaries, by rescuing the zygotic lethality of sax alleles then maintaining the females at non-heat shock temperatures.
