Detailed Description

Statement

Reference

Homozygous adult escapers are occasionally seen. These escapers do not show abnormalities in the thorax or in wing hair polarity. The vast majority of ommatidia are wild type in eyes of adult escapers, but some ommatidia are missing photoreceptors and a small fraction show defects in R3/R4 fate specification. The adult escapers are grossly uncoordinated and on eclosion they immediately fall into the food and die. If the flies are retrieved before they get stuck in the food, they are unable to fly and show a severely delayed righting reflex and although they appear to walk normally, they have impaired climbing behaviour.

Additional Comments

Genetic Interactions

Statement

Reference

bdg¹⁶⁴ dominantly suppresses the ommatidial polarity defects of stan^sev.PU, dgo³⁸⁰ mutants.

bdg¹⁶⁴ dominantly enhances the ommatidial polarity defects of Vang^sev.PR, dgo^sev.PU or dsh¹ mutants.

The ommatidial polarity defects caused by dsh^sev.PU or fz^sev.PU are not modified by one copy of bdg¹⁶⁴.

Homozygosity for bdg¹⁶⁴ enhances the ommatidial polarity defects caused by homozygosity for Vang^stbm-6, Vang^stbm-153 or stan^frz3.

Homozygosity for bdg¹⁶⁴ enhances the ommatidial polarity defects caused by fz²⁰/fz¹⁹.
