Genetic mapping information

The 2L:22536884..22943135 release 6 coordinates of the left breakpoint are estimates. The left extent corresponds to the right end of RpL5, because Df(2L)C' heterozygotes do not show the Minute phenotypes that would be seen if this haploinsufficient gene were deleted. The right extent corresponds to the right end of lt, which published results say is deleted.

The right breakpoint of Df(2L)C' is shown at release 6 coordinate 2L:23515712 , the right end of the 2L genome assembly, because Df(2L)C' extends into 2L centric heterochromatin.

Comments on Cytology

Complex rearrangement with additional heterochromatic material.

Deficiency of basal heterochromatin.

In combination with other aberrations

Heterozygotes with In(2LR)U are viable.

NOT in combination with other aberrations

The Df(2L)C' 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(2L)C' results in 0.7% X chromosome nondisjunction and 0.0% fourth chromosome nondisjunction in In(1)FM7/X ; svspa-pol females.
