The Df(2R)nap9 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).
No second site non-complementing phenotype with zipEbr and zipmhc-c6.1.
The left Df(2R)nap9 breakpoint lies within dpr12 or Or42b or in the region between dpr12 and Or42b, and lies in the range 2R:1685751..1740465 (R5) (predicted cytology: 41F11-42A1).
The right Df(2R)nap9 breakpoint likely lies within Tsp42Ec or Tsp42Ed or in the region between these genes, and lies in the range 2R:2887736..2897448 (R5) (predicted cytology: 42B2).
