A Selective Screen to Recover Chromosomal Deletions and Duplications in Drosophila Melanogaster
AUTOR(ES)
Gubb, D.
RESUMO
A screen is described that will select for breakpoints within a restricted chromosomal region in Drosophila. The aberrations recovered can be used to construct chromosomes carrying synthetic duplications and deletions. Such chromosomes have applications in the mapping of complementation groups at both the genetic and molecular level. In particular, breakpoints recovered after P element hybrid dysgenesis tend to be associated with P element insertion sites. Such aberration breakpoints can be genetically mapped, as synthetic deletions, and then used as transposon-tagged sites for the recovery of genomic clones.
