Comments on Cytology

The left Df(2R)H3E1 breakpoint lies within mtt or to the right of mtt in the range 2R:4366981..4421817 (R5) (predicted cytology: 44D1-44D2).

The right Df(2R)H3E1 breakpoint lies within CG8213 or CG34350 or in the region between them, and lies in the range 2R:4858050..4881316 (R5) (predicted cytology: 44F12-45A1).

Left limit of break 1 from polytene analysis (FBrf0086252) Right limit of break 1 from inclusion of ptc (FBrf0089219) Limits of break 2 from polytene analysis (FBrf0086252)

The Df(2R)H3E1 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(2R)H3E1 results in 0.9% X chromosome nondisjunction and 0.0% fourth chromosome nondisjunction in In(1)FM7/X ; svspa-pol females.

Fails to complement Df(2R)44CE for lethality and show the ptc phenotype but germ cell migration is normal.
