In combination with other aberrations
Males carrying In(1)l-v231 and Dp(1;f)1346 show 14% viability relative to controls.
The X heterochromatin in Dp(1;f)1346 appears to suppress the eye colour variegation phenotype of In(1)wm4.
The X heterochromatin in Dp(1;f)1346 appears to suppress the eye colour variegation phenotype of In(2)bwVde2.
Dp(1;f)1346/In(1)sc4Lsc8R lethal
NOT in combination with other aberrations
