Comments on Cytology

The left Df(3R)p-XT103 breakpoint lies within CG31369 either within the intronic gene Or85b or to its left in the range 3R:4245820..4336007 (R5) (predicted cytology: 85A1-2). The right Df(3R)p-XT103 breakpoint lies within CG11966, CG11967 or RagA or in a region between them, and lies in the range 3R:4778677..4809191 (R5) (predicted cytology: 85B8-C1).

Df(3R)p-XT103 embryos have disrupted tracheal branches.

The Df(3R)p-XT103 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)p-XT103 results in 8.9% X chromosome nondisjunction and 1.0% fourth chromosome nondisjunction in In(1)FM7/X ; svspa-pol females.

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

Deficient embryos show an uninterpretable mutant midgut phenotype.

One copy of osk causes to the formation of 10-15 pole cells.
