Genetic mapping information

Breakpoint(s) molecularly mapped

Left DNA breakpoint at -67.1 to -68.3 kb, the origin of the map being the EcoRI site immediately distal to Adh (Chia, Karp, McGill and Ashburner, 1985, J. Mol. Biol. 186: 689-706).

    In combination with other aberrations

    Weakly suppresses the zeste phenotype in a z1 w11E4; Tp(1;2)TE35B homologue.

    NOT in combination with other aberrations

    Chromosome acts as a weak trans-suppressor of a physical interaction between tandemly duplicated copies of w+, an interaction that is required for the suppression of genes by z1.

    homozygous lethal in pupal stage. Lethal over Sco and most Sco revertants, but semilethal with Scorv27. Also semilethal with noc alleles and with some el and noc alleles. Lethality maps between left breakpoints of Df(2L)A446 and Df(2L)A267. Associated with warped wing and pale scutellum phenotypes (Ashburner et al., 1983).

    Revertants of the Scorv1 lethal interaction with nocTE35B include In(2LR)Scorv1-DV1 and seven other derivatives, which are not further rearranged, designated DV4, DV5, and DV6 (EMS induced) and DV9, DV10, and DV11 (γ ray induced) (Ashburner, unpublished).
