Comparative genomic hybridization (CGH) assays and compositions for use in practicing the same are provided. Aspects of the methods include first preparing genomic templates from an initial genomic source by using precursors of circular template nucleic acids, e.g., padlock probes. The precursors include first and second domains that are at least partially complementary to substantially neighboring regions of a genomic domain of interest. In certain embodiments, the methods include an isothermal amplification step, e.g., a rolling circle amplification step. The resultant templates may then be employed to produce target nucleic acid populations, e.g., for use in CGH applications. Also provided are kits for use in practicing the subject methods.
