      Statement
      Reference

      E(ftz)21422142 dominantly enhances the lethality of ftz5/ftz13 animals at 26.5oC (fewer animals survive to adulthood). This interaction has a strong maternal effect with a weak or no zygotic effect. E(ftz)21422142 dominantly enhances the segmentation defects seen in ftz5/ftz13 embryos at 27.5oC; 93.1% of the embryos have segment defects and 13.2% have at least 3 ftz-dependent segments affected.
