Genetic mapping information

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

Comments on Cytology

The left Df(2L)r10 breakpoint lies within genes CG4161 and sna or in the region between them, in the range 2L:15434573 .. 15476957 (R5) (Predicted cytology: 35D2).

The right Df(2L)r10 breakpoint lies within CG5968 or CG42389 or in the region between them, in the range 2L:16549467..16559961 (R5) (Predicted cytology: 36A4-36A5) based on the following evidence.

In combination with other aberrations

Df(2L)r10/Df(2L)H20 results in almost complete lethality.

NOT in combination with other aberrations

Df(2L)r10 heterozygotes show increased dietary copper tolerance compared with wild-type.

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

The Df(2L)r10 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).

Heterozygosity for Df(2L)r10 results in 14.5% X chromosome nondisjunction and 8.5% fourth chromosome nondisjunction in In(1)FM7/X ; svspa-pol females.

In embryos heterozygous for Df(2L)r10, leading edge (LE) cells are observed in a single row; however the ring of LE cells are positioned slightly more dorsally than in wild-type and appear smaller to account for the reduced area of the amnioserosa tissue.

Df(2L)r10 in combination with a pair of introgressions from D.simulans spanning 30F1-31E7 to 35D7-36A14 Dsim\Int(2L)S and 21A1 to 22D1--23A2 Dsim\Int(2L)D produces sterile male flies. These flies are female sterile.

Does not cause unconditional lethality in hybrid females when heterozygous with D.simulans chromosome.

No second site non-complementing phenotype with zipEbr and zipmhc-c6.1.

Shows no maternal enhancement of dpphr4.

Midgut development of mutant embryos is wild type.
