| 摘要 |
The present invention features a collection of at least four nucleic acid probes. The probes each comprises a segment, the entirety of which hybridizes under low stringency conditions to at least a first gene of a first species and a second gene of a second species, wherein the hybridizing probes correspond to different genes of the first or second species, and the first and the second genes are orthologous to each other. In some embodiments, the entirety of the segment is at least 60% (e.g., 65%, 70%, 80%, 90%, or 95%) identical to the first gene and the second gene.
