Homozygotes are sterile. Semi-lethal. Heteroallelic In(3)Msu1/In(3)Msu2 flies are recovered at 4% of the expected value. Male heteroallelic escapers are recovered at about 50% the rate of female escapers. Modifies the phenotype of wa such that a mottled stripe of brilliant red at the posterior of the eye. In(3)Msu1/In(3)Msu2 escapers act as strong suppressors of wa and also recessive enhancers of synaptic-dependent gene expression at w. Testes of wa, In(3)Msu1 also show increased pigmentation with respect to wa. In(3)Msu1/In(3)Msu2 enhances the zeste effect of z1, wzl, producing white eyes, but has no effect on z1, wzm.
Attempts to generate revertants with γ ray and ethyl methanesulfonate were unsuccessful.
There are multiple breaks on the third chromosome, but both In(3)Msu1 and In(3)Msu2 have inversions with breaks near the centric heterochromatin and 98F.
