Zzzz\CAGQ79.GMR.Tag:FLAG has visible phenotype, enhanceable by Scer\GAL4GMR.PS
Zzzz\CAGQ79.GMR.Tag:FLAG has eye phenotype, enhanceable by Scer\GAL4GMR.PS
Expression of TER94Scer\UAS.cHa under the control of Scer\GAL4GMR.PS enhances the rough eye phenotypes caused by Zzzz\CAGQ79.GMR.T:Zzzz\FLAG.
Zzzz\CAGQ79.GMR.T:Zzzz\FLAG is unstable with respect to the number of CAG trinucleotide repeats; when stocks containing Zzzz\CAGQ79.GMR.T:Zzzz\FLAG are maintained for several generations, expansion or shortening of the CAG repeat length can be seen.
