G967F
A double nucleotide substitution in codon 967 causes a Gly to Phe mutation. One of two amino acid substitutions in mutant.

A965E | msl-1-PA; A965E | msl-1-PB
A965E
One of two amino acid substitutions in mutant.
msl-1AFG has little or no effect on the fraction of red eye tissue present in males homozygous for P{GMroX1}75C.
The ability of P{GMroX1}75C (which carries roX1t4.9) to partially rescue the lethality of roX1ex6/Df(1)52 males is suppressed if the males are also heterozygous for msl-1AFG.
