These are notes on things I came across in FlyBase Aberration records as I worked on the new Class assignments. FBab0027958 Df(2L)sna2.4LGYLR Df is sna- cact-, dup is 33B1;35C1-2, therefore presumably deficient for at least 35D2;35F9-11 FBab0024736 T(2;3)sna2.40 This is a transposition, so should be Tp(2;3)sna2.40. The deficiency seg is sna- and the duplication seg is sna+ \- ref is DIS 66 (1987), p. 259, where the genotype of stock D710, Df(2L)sna2.40L Dp(2;2)GYLR/CyO; Dp(2;3)sna+2.40/TM3, Sb, makes it clear that the parental T(2;3)sna2.40 must be a Tp (and that the transposed segment carries sna).
