Revised cytological breakpoints for Df(2L)spd and Df(2L)XE-2750
Df(2L)XE-2750
28A4 present, 28B1,2 doublet absent, 28C1 absent, 28D1,2 doublet
present. It's also likely that 28C7,8 present, but conservative
interpretation is 28A5-B1;28C1-9.
Df(2L)spd
Though reported in literature as a simple deletion, it is really a
deficient inversion. The breakpoints are
26A6-B1;27E1-3;28B1-3. Inversion breakpoint between 26A6 and 26B1.
27E1,2 doublet may be partially deleted. 27E3 definitely deleted.
Deletion breakpoint between 26B1,2 and B3. 28C1 present. Therefore,
cytology is 27E1-3;28B1-3;26A6-B1 with the deletion between the first
two breakpoints.
