11bp deletion which results in the last 61 amino acid residues of msl-1 being replaced with 25 amino acid residues from another reading frame.
An 11 bp deletion that causes a frameshift affecting the final 61 aa of msl-1.
msl-1F979Z dominantly increases the fraction of red eye tissue present in males homozygous for P{GMroX1}75C, but does not increase eye pigmentation in females carrying P{GMroX1}75C.
P{GMroX1}75C (which carries roX1t4.9) is still able to partially rescue the lethality of roX1ex6/Df(1)52 males if the males are also heterozygous for msl-1F979Z.
