In combination with other aberrations

Inferred to overlap with: Df(2L)3G.

Lethal in combination with Df(2L)3G.

Inferred to overlap with: Df(2L)JS25.

Fails to complement T(2;3)DTD46.4.

NOT in combination with other aberrations

One copy of Df(2L)JS17 is unable to suppress position effect variegation (PEV) at the w locus caused by In(1)wm4.

One copy of Df(2L)JS17 is unable to suppress 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.

The Df(2L)JS17 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).

Maternal enhancement of the dpphr4 lethality. The lethal interaction is due to a loss of dorsal-most fates in the embryos, demonstrated by loss of amnioserosa cells.

Maternal effect enhancement of dpp mutant phenotype.
