Genetic Loss- and Gain-Of-Function Mosaic Analysis Was Used to Elucidate

Essay

Genetic loss- and gain-of-function mosaic analysis was used to elucidate the roles of several proteins in medulla layer-specific targeting.
A. What outcome(s) would one expect in R7 vs. R8 cells from the experimental misexpression of Frazzled specifically in R7 cells?
B. What outcome(s) would one expect in R7 vs. R8 cells from a mosaic experiment in which Senseless was removed from a presumptive R7 cell?
