Chromosome-Breaking Ds Sites

--M. G. Neuffer

In the 1986 News Letter (60:55), we described efforts to obtain chromosome Ds-transposition sites with appropriate markers on 16 chromosome arms. Two arms (6S and 8S) did not have good markers, and two arms (9S and 10L) already had such identified sites. We can now report considerable success as indicated by the entries listed below.
