Subject: Aberrations in the Mid-America Stock List
Background: We asked Dan if he could identify any of the aberrations from the Mid-America stock list that weren't in FlyBase 
or provide any additional information on some that were in FlyBase. Information he provided that is relevant to FlyBase follows. 
Information communicated:
1. Dp(1;YL)scS13
"I found this Dp. It is an independent occurrence, but there's not much to recommend keeping it. As far as I knew it was long
gone."
2. Dp(1;YL)y+ T0 
"I almost couldn't dredge up the identity of T0. It is the result of a recombinant between YS and the distal heterochromatin of 
In(1)sc8. It is from my thesis in Genetics 40 page 28."
3. Dp(1;YS)scV1
"Dp(1;YS)scV1 is an interesting chromosome. It was derived from an exchange between proximal YS and the proximal Xhet 
of the pericentric inversion, In(1LR)scV1 and therefore has y+ and ac+ on the other side of the centromere from YS."
4. Dp(1;YL)y+YL, also known as FR2 and y+YL.
"The reason that Novitski called this a fragment is that it seems to be a derivative of only the centromere end of C(1;Y)1. The 
fact that it is bb+ indicates that the exchange appending YL to In(1)EN involved the short arm of Y distal to bb+, since 
In(1)EN carries bb at both ends."
5. YSX.P0 
"Remarkably, this is another derivative from my thesis. It resulted from an exchange between YS and the distal heterochromatin 
of In(1)sc8LENR. Genetics 40, page 28."
