Flies heterozygous for the deletion do not show a Minute bristle phenotype.

Heterozygosity for Df(2R)stan2 results in 6.6% X chromosome nondisjunction and 10.9% fourth chromosome nondisjunction in In(1)FM7/X ; svspa-pol females.

The Df(2R)stan2 chromosome acts as a dominant weak suppressor of telomeric silencing (assayed using the effect of the chromosome on the eye colour phenotype of flies carrying "P{wvar}KR3-2", a stable "brown-red" variant of the P{3'WP-2,wvar}2Lt insertion), but this is a false positive result (the suppressor is not within the bounds of the deficient region) because the region of the deficiency is covered by a combination of nonsuppressing deficiencies and deficiencies with suppressors that map to the 2L tip.

"46F1;47B9" was stated as revision.
