We are looking for genomic DNA, flies, or flies in EtOH to prep genomic DNA for two Drosophila species: D rubida and D. obscura, to allow a PCR confirmation study of presence/absence predicted by computational analyses of germ line stem cell essential (in D melanogaster) genes across the genus based on current full genome assemblies. Please contact us if you can help! Best, Chip Aquadro and Luke Arnce, Cornell University cfa1@cornell.edu la424@cornell.edu "Charles F.
