Comments on Cytology

Resembles In(1)sc8 in mitotic prophase. In(1)sc8 with the distal uninverted euchromatic region carrying the normal alleles of pch through ac replaced by KS. YSX, In(1)sc8, KS pch-ac- sc8.

Affected Genes Inferred by Location (0)
    If no genes are listed here, it may be because the affected region is very large. The JBrowse insert above may show an error for the same reason, and other FlyBase tools such as CytoSearch may also fail for large regions. You can contact FlyBase for more help.
    In these cases, there will be no "Export to Hitlist" button to the left.

    Infrequent product of spermatogonial exchange between YS and the distal inverted heterochromatic segment of In(1)sc8. The incidence of recovery increased twenty-fold in genotypes undergoing ribosomal DNA magnification <up>e.g., In(1)sc8, bbl sc8/Ybb</up>, but decreasing with successive generations of magnification (Ritossa, 1973). Deficiency recovered in single crossover between In(1)sc8 and In(1)EN, i.e., 'In(1)sc8LENR'.
