nej0.3 does not show any dominant suppressor (Su(var)) or enhancer (E(var)) of variegation activity. Any second site Su(var) mutations on the original chromosome can be separated from nej0.3 by recombination. Additional copies of nej+mSa (or nejT:SV5\V5) fail to rescue the Su(var) phenotype of the original chromosome carrying nej0.3.
