In combination with other aberrations
Df(3R)jar322 is lethal in combination with Df(3R)crb-F89-4.
The position effect variegation of w seen in In(1)wm4 is suppressed by one copy of Df(3R)crb-F89-4.
NOT in combination with other aberrations
Flies heterozygous for the deletion do not show a Minute bristle phenotype.
The Df(3R)crb-F89-4 chromosome does not act as a dominant 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).
Heterozygosity for Df(3R)crb-F89-4 results in 1.9% X chromosome nondisjunction and 0.0% fourth chromosome nondisjunction in In(1)FM7/X ; svspa-pol females.
Suppresses the ommatidial polarity phenotype of dshhs.sev.B. Suppresses the ommatidial polarity phenotype of msnEP549 when driven by Scer\GAL4hs.2sev.
