|Class of aberration (relative to progenitor)|
|Formalized genetic data||Zhr << bk1 << l(1)sc << bk2 hits ABO-X|
|Genetic mapping information|
Breakpoint(s) molecularly mapped
Left breakpoint between DNA coordinates +24.0 and +25.8 (Campuzano et al., 1985). 0 is an arbitrarily chosen EcoRI site in the scβ segment of ASC; positive values to the left (Carramolino, Ruiz-Gomez, Guererro, Campuzano and Modolell, 1982, EMBO J. 1: 1185-92).
|Comments on Cytology|
The proximal breakpoint is in or near the ABO-X heterochromatic region that maternally interacts with the abo gene product.
|Gene Deletion & Duplication Data|

|NOT in combination with other aberrations|
Homozygous females show a loss of tergite chaetae.
Maternal and zygotic interactions between abo and In(1)sc4 (Malva, Labella, Manzi, Salzano, Lavorgna, De Ponti and Graziani, 1985, Genetics 111: 487-94). In(1)sc4/+ female produces about 6% exceptional males from 4-strand double exchange. Secondary exceptions about 4%.
