Detailed Description
Statement
Reference

One copy of Psce22 is unable to suppress position effect variegation (PEV) at the w locus caused by In(1)wm4.

One copy of Psce22 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 chromosome.

Lethal over Psc1, shows some degree of viability over deficiencies for the region. Adult survivors of transallelic combinations of "hopeful" alleles show homeotic phenotypes. The wing is often half or less their normal size, bulbous, arched upward and curved inward in the shape of a cashew nut. The posterior compartment of the wing is more severely affected than the anterior compartment. Alula can be reduced or missing, posterior wing margin is missing and the flanking wing blade is eroded. This homeotic phenotype resembles that of the Cbx mutations, and is dominantly enhanced by Su(z)24. Enhances z1 eye color.

No homeotic phenotype and the mutation cannot enhance the homeotic phenotypes of Pc group mutants (FBrf0049524).

Member of the "hopeful" class of Psc alleles, i.e. shows some degree of viability in trans to at least one of the "hapless" alleles.
