chif1 homozygous mutant animals do not exhibit any defects in their scutellar or wing-margin bristles when compared to controls.
Hemizygous females produce eggs with thin chorions. Hemizygotes have rough eyes and thin scutellar bristles. Chorion gene amplification is less than 7% of normal.
Eggs have no dorsal appendages and have a thin, fragile cuticle: defective in chorion gene amplification.
female-sterile thin, fragile chorions and remain unfertilized. homozygous females lay eggs which have
