Has no effect on the frequency of X-Y chromosome nondisjunction seen in Df(1)X-1-53B males.
Df(2R)cn83c/Df(2R)CA53 embryos are usually wild-type, but sometimes have segmentation defects and denticles in the third thoracic segment that resemble abdominal denticles. Df(2R)CA53/Df(2R)cn83c ; Scm1/+ embryos lack terminal structures and are U-shaped. Denticle belts of the 3rd to 7th abdominal segments are transformed posteriorly.
Flies heterozygous for the deletion do not show a Minute bristle phenotype.
The Df(2R)CA53 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 this deletion has no effect on the mutant ovarian phenotype of ovoD2.
1-3% of male flies carrying Df(2R)CA53 have extra sex combs.
Ocelli small in heterozygotes.
Durrant.
