This deletion removes a single ribosomal protein-coding gene (though other genes are also removed).
Lethal in combination with Df(2L)BSC156.
Fails to complement T(2;3)DTD46.4.
Homozygous lethal.
Flies heterozygous for the deletion show a Minute bristle phenotype.
The Df(2L)C144 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(2L)C144 results in 2.3% X chromosome nondisjunction and 0.0% fourth chromosome nondisjunction in In(1)FM7/X ; svspa-pol females.
Wild-type clones made in the ovaries of a mutant female, are significantly larger than clones of heterozygous mutant cells. This size difference is greater in clones initiated at 48 hours after egg laying (AEL) than 2 hours AEL.
No second site non-complementing phenotype with zipEbr and zipmhc-c6.1.
The left breakpoint lies within CG3528 or CG3515 or in the region between them, and lies in the range 2L:2517598..2551864 (R5) (predicted cytology: 22F4). The right breakpoint lies within Rbp9, and lies in the range 2L:2955279..2961962 (R5) (predicted cytology: 23C3).
PCR amplification of the Chd1 genomic region from flies carrying Df(2L)C144 over a large Chd1 deletion shows that the right limit of breakpoint 2 for Df(2L)C144 lies to the left of Chd1.
Left limit of break 1 from non-inclusion of oaf (FBrf0076536) Right limit of break 1 from inclusion of Drp1 (FBrf0076536) Limits of break 2 from polytene analysis (FBrf0080380)
