Df(2L)b89e12 is b- -- l(2)34De-, l(2)34Dg+
i.e. it orders the previously unordered De and Dg.

Subject: Re: Alexandrov
we don't have a 'Df(2L)b89e12'
we only have a
\*a T(2;3)b89e12
Is this what you mean?

'Fraid so
T(2;3)b89e12 is deleted for b, 34Dc, 34Dd, 34Df, 34De but not 34Dg.

So its a three break event in fact, a Deficient Translocation.
Is the Df visible or does it still look like a simple two break event?
The breaks we have are basically \*B 34D4;79C3, but if you could add a third
break to that you'd make a curator happy.

We haven't done the cytology - Alex just says 34D4;79C3 and I suspect Df
34D4; approx 34D6 would be easily missed within a T(2;3).
