Subject: Cytological Breakpoints of Df(2L)ade3
The Stock Center received a stock of Df(2L)ade3 from Betsy Wilder, U. of
Pennsylvania, which her lab used in Cohen et al., 2002, Dev. Cell 2(4):
437-448 (FBrf0146974). She said the deletion originated with the work of
Tiong and Nash (Genetics 1990  124:889--897 ; FBrf0051986). My polytene
squashes showed that the deletion has breakpoints 27D1-2;27F1-2. The
deletion breaks within both doublets to form a thick fusion band.
