The characterization of chromosome breaks in Drosophila melanogaster. II. Molecular analysis of gamma-ray-induced deficiencies in the 14F-15A region

In the previous paper of this series, a total of 446 mutations of the para gene were isolated following gamma- or X-irradiation. Of these, 180 were shown to be chromosome deficiencies. In this analysis we examine the molecular distribution of breakpoints in a subset of strains 38] which have an endpoint in the 14F-15A5 region. We find that although the breakpoints are distributed throughout the entire region, there is some regional specificity to the distribution of those endpoints.
