      Reference

      The adult lifespan of nec9 homozygotes is greatly reduced at 18[o]C, 25[o]C or 29[o]C temperature, as compared to wild-type flies. The adult lifespan of nec9/nec2 trnsheterozygots is greatly reduced at 25[o]C or 29[o]C temperature, as compared to wild-type flies.

      (Green et al., 2003)

      Homozygotes are pharate adult lethal or die within 24 hours of eclosion.
