The comparative biology of second sex ratio evolution within a natural population of a parasitic wasp, Nasonia vitripennis.

abstract：:We describe a second-generation deficiency kit for Drosophila melanogaster composed of molecularly mapped deletions on an isogenic background, covering approximately 77% of the Release 5.1 genome. Using a previously reported collection of FRT-bearing P-element insertions, we have generated 655 new deletions and verifi...
