      chif1 homozygous mutant animals do not exhibit any defects in their scutellar or wing-margin bristles when compared to controls.

      (McDaniel et al., 2020)

      Hemizygous females produce eggs with thin chorions. Hemizygotes have rough eyes and thin scutellar bristles. Chorion gene amplification is less than 7% of normal.

      (Landis and Tower, 1999)

      Eggs have no dorsal appendages and have a thin, fragile cuticle: defective in chorion gene amplification.

      (Schupbach and Wieschaus, 1991)

      female-sterile thin, fragile chorions and remain unfertilized. homozygous females lay eggs which have
