Looking for B[S]-marked attached-XY

[Kevin Cook]

Dear Chromosome Mechanics---

I am looking for an attached-XY chromosome of the form XYS.YL with an 
intact B[S] appended to YL.  Such a chromosome would probably be the 
Ts(XLt;YLt) from a translocation between a normal X and Dp(1;Y)B[S]Yy[+] or 
Dp(1;Y)B[S]----in other words, it would have an X heterochromatin break and 
a break distal to the male fertility factors on YS.  The perfect chromosome 
would have its X heterochromatin break proximal to bb, but I'll take what I 
can get.

If you have these flies, I'd love to get a sample.  The only good 
B[S]-marked X^Y I've located has the Bithorax complex inserted at the base 
of the X.  It may work for my purposes, but I'd like to find something simpler.

Many thanks,
Kevin
