      Detailed Description
      Statement
      Reference

      Clones in the eye contain few or no photoreceptors. The few that remain are found in posterior regions of the clone, and die later in development. Clone size is normal and clones do not interfere with the spread of differentiation-promoting signals. Antennal disc cell fates are also altered.
