Site of nucleotide substitution in mutant inferred by FlyBase based on reported amino acid change.
One copy of Su(z)2eos is unable to suppress position effect variegation (PEV) at the w locus caused by In(1)wm4.
One copy of Su(z)2eos moderately suppresses the telomeric position effect (TPE) in stocks carrying a variegating P{hsp26-pt-T}39C-5 insertion at the telomere of the left arm of chromosome two.
Shows no dominant effect on telomeric Position Effect Variegation (PEV) in stocks carrying a variegating w+mW.hs allele at the telomeres of the second and third chromosomes.
Hemizygotes die as larvae/pupae.
Has no effect on the frequency of X-Y chromosome nondisjunction seen in Df(1)X-1-53B males, but acts as a meiotic drive suppressor, suppressing drive against the X and Y chromosomes in these flies.
Viable in trans to alleles of Psc and Su(z)2, though in some cases viability is reduced. Su(z)31 and Su(z)3eos show partial complementation.
