Expression of cswhs.2sev in a wild-type background does not affect the ommatidial array in the eye.
Rescues the zygotic lethality of csw13-87/Y and csw6/Y males. Also has maternal csw+ function; homozygous csw13-87 females carrying cswhs.2sev produce wild-type progeny.
Rescues the lethality and eye phenotype associated with cswEsev1A-eOP.
