By temporarily modifying the function of Polycomb Group (PcG) proteins—which play an essential role in development—the researchers obtained fruit fly lines having the same DNA sequence but different eye colors.

It is observed in both transgenic and wild-type lines and can be modified by environmental conditions such as ambient temperature.
