Df(2R)trix embryos from heterozygous mothers show segregation defects in anaphase and telophase as judged by the presence of chromatin bridges. These embryos show a higher level of "nuclear fallout", a process that removes nuclei with abnormal mitoses, than wild-type embryos. Fallout nuclei tend to be observed in pairs or clusters. There is no evidence of metaphase defects in these embryos and have a late telophase appearance.

(O'Dor et al., 2006)

Heterozygosity for Df(2R)trix results in 2.2% X chromosome nondisjunction and 1.0% fourth chromosome nondisjunction in In(1)FM7/X ; sv^spa-pol females.

(Harris et al., 2003)

Enhances the trx-G homeotic transformations of Df(3R)red1. Strongly enhances both the extra sex comb and abdominal segment transformation phenotypes of Pc⁴.

Does not cause unconditional lethality in hybrid females when heterozygous with D.simulans chromosome.

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

(Duffy et al., 1996)

Suppressor of the dosage dependent (two or more copies of P{sev-svp1} or P{sev-svp2}) transformation of cone cells into R7 photoreceptors and at a lower frequency R7 cells into outer photoreceptors.

Deficient embryos show a mutant midgut phenotype: central and posterior constrictions absent.

Heterozygosity for this deletion has no effect on the mutant ovarian phenotype of ovo^D2.

Other Comments

The Df(2R)trix chromosome acts as a dominant weak suppressor of telomeric silencing (assayed using the effect of the chromosome on the eye colour phenotype of flies carrying "P{w^var}KR3-2", a stable "brown-red" variant of the P{3'WP-2,w^var}2Lt insertion), but this is a false positive result (the suppressor is not within the bounds of the deficient region) because the region of the deficiency is covered by one or more nonsuppressing deficiencies.
