Genetic mapping information
Comments on Cytology

The left Df(3R)Tl-P breakpoint lies within CG14551 or dys or in a region between these genes, and lies in the range 3R:21885676..21903734 (R5) (predicted cytology: 96F10-12).

The right Df(3R)Tl-P breakpoint probably lies within side, CG13978 or Cyp6a18 or in a region between these genes, and lies in the range 3R:23214330..23305922 (R5) (predicted cytology: 97F8-98A2).

In combination with other aberrations

Inferred to overlap with: Df(3R)Espl3.

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

NOT in combination with other aberrations

The Df(3R)Tl-P 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)Tl-P results in 3.7% X chromosome nondisjunction and 5.6% fourth chromosome nondisjunction in In(1)FM7/X ; svspa-pol females.

Causes inviability or low viability 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.

Heterozygotes with Df(3R)Dl-BX6 are fully viable.

Wild type nonanol phenotype; repulsion.

Dominantly causes tergite defects in less than 50% of run3 heterozygotes.

Midgut development of mutant embryos is wild type.

Homozygous embryos have smaller heads than normal.

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

heterozygous females viable heterozygous females fertile
