Embryos derived from homozygous female germline clones have fusions of the dorsal head and thorax, giving the embryos a "comma" appearance.
ftz-f1[+]/ftz-f13443 is an enhancer | maternal effect of partially lethal | heat sensitive phenotype of ftz5/ftz13
ftz-f1[+]/ftz-f13443 is an enhancer of embryonic segment phenotype of ftz5/ftz13
ftz-f13443 dominantly enhances the lethality of ftz5/ftz13 animals at 26.5oC (fewer animals survive to adulthood). This interaction is a maternal effect. ftz-f13443 dominantly enhances the segmentation defects seen in ftz5/ftz13 embryos at 27.5oC; 98.5% of the embryos have segment defects and 35.1% have at least 3 ftz-dependent segments affected.
