Dear Rachel: All the revertants deleted the proximal junction of In(3R)pugD. The two break points for In(3R)pugD are 86C3-4 and 95D1-6. The deleted segments of the revertants are as followed: rv7: 85E15-pugD-95C8. rv1: 86A1-pugD-95B3. rv17*: 86A8-pugD-94F3. rv10: 86B6-pugD-94F4. rv5: 86C3-4-pugD-95C8. rv15**: 86C3-4-pugD-95C5. rv2: 86C3-4-pugD-95B4. rv6: 86C3-4-pugD-95A5. rv4: 86C3-4-pugD-94F3. \*: the corresponding region is translocated to the Y chromosome giving rise to Dp(3;Y)pugD. \**: also contains an In(3R)82E3-4;91C3-4. Please feel free to contact me for further questions. Sincerely, Yikang Rong > Dear Kent, I have just started curating your Genetics paper Rong and Golic, 1998, Genetics 150(4): 1551--1566. Dominant defects ..... I notice that Figure 4 includes several cytologically defined deficiency revertants but unfortunately I do not see text descriptions of the break points. This means that the cytology is impossible for us to capture for FlyBase. (We do not infer cytologies from diagrams, as a policy, since it is too prone to differences of interpretation between author and curator). Would you be able to tell me with breakpoints for the following chromosomes from Figure 4? The aberration records that result in FlyBase will be so much more useful with the breakpoint information. rv7 rv1 rv17 rv10 rv5 rv15 rv2 rv6 rv4 With best wishes, Rachel.
