Comments on Cytology

Three euchromatic bands visible in salivary chromosomes (FBrf0013322). Prophase chromosomes show the presence of an extra Hoechst-bright segment (BSXh) appended to the end of YL and separated from it by a non-fluorescent junction gap (BSXhj) (FBrf0039037).

A Y chromosome with its long arm marked terminally with BS.

    In combination with other aberrations

    No defect in the gross morphology of distal legs is seen when Df(1)B clones are induced in flies carrying Dp(1;Y)BS.

    NOT in combination with other aberrations

    Causes extreme B phenotype; presence readily scorable in +/+, B/+ and + but not in B or B/B constitutions. Viability and fertility of X/Dp(1;Y)BS, X/Dp(1;Y)BS/Dp(1;Y)BS and X/X/Dp(1;Y)BS good. Eyes of X/Dp(1;Y)BS detectably wider than those of X/Dp(1;Y)BS/Dp(1;Y)BS.

    Good viability and normal disjunction from an X chromosome in the male.

    Notes on Origin

    X ray induced deletion of the euchromatin (including mal+) from a recombinant carrying the left end of the XP4D element of T(1;4)BS = T(1;4)15F9-16A1;16A7-B1;102F and the right end of XYL.YS.
