Comments

This deletion removes a single ribosomal protein-coding gene (though other genes are also removed).

No effect on In(1)wm4h position-effect variegation.

(Wustmann et al., 1989)
NOT in combination with other aberrations

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

(Marygold et al., 2007)

Heterozygosity for Df(2R)ST1 results in 1.9% X chromosome nondisjunction and 0.8% fourth chromosome nondisjunction in In(1)FM7/X ; svspa-pol females.

(Harris et al., 2003)

Homozygotes exhibit tracheal defects, with losses of the dorsal drunk, severely disrupted transverse connectives and absences of the visceral branch.

(Sedaghat et al., 2002)

Heterozygosity for this deletion has no effect on the mutant ovarian phenotype of ovoD2.

(Pauli et al., 1995)

The ocelli are reduced in size. The number of anterior postalar bristles and ocellar bristles are reduced. The pattern of the interocellar microchaetae is disturbed.

(Ashburner et al., 1981)

Heterozygotes have small ocelli (Ashburner).

Other Comments
 

The Df(2R)ST1 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 one or more nonsuppressing deficiencies.

(Mason et al., 2004)

Mistakenly interpreted as carrying a noc allele induced simultaneously.

(Gubb et al., 1985, Ashburner et al., 1981)
