Historically important set of X;Y translocation stocks; few of these stocks still extant.

No defect in the gross morphology of distal legs is seen when Df(1)Bar clones are induced in flies carrying Dp(1;Y)BarS.
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)BarS, X/Dp(1;Y)BarS/Dp(1;Y)BarS and X/X/Dp(1;Y)BarS good. Eyes of X/Dp(1;Y)BarS detectably wider than those of X/Dp(1;Y)BarS/Dp(1;Y)BarS.
Good viability and normal disjunction from an X chromosome in the male.
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.
