Abstract: The present invention discloses a designing strategy for constructing a set of probes useful for analyzing all or most prokaryotic and eukaryotic genomes. A set of capture probes with optimal fingerprinting properties and highly representative of all possible sequences of an organism can be selected by six sequential steps. Fingerprinting potential of such probes is validated by phylogenetic analysis, which generates results that strongly correlate with phylogenetic trees produced by sequence alignment. The probes generated by the instant methods can be used for detecting an organism, for establishing phylogenetic relationships between different organisms, for detection of single nucleotide polymorphisms and a wide variety of other applications that require genetic analysis.
