A. Diagrammatic representations of two plates with high rates of plate wide systematic overlapping BAC fingerprints, but not high rates of putative inconsistent BACs. BAC colour coding is as follows; fingerprint overlap and BAC end sequence overlap – green, fingerprint overlap and BAC end sequence known, but no overlap – cyan, fingerprint overlap and BAC end sequence overlap not known – yellow. Red outline fingerprint overlap greater than 90%. Black lines join wells containing BACs with overlapping fingerprints. B. Plot of the frequency of BACs from the same plate that overlap in the fingerprint map and are located on the same row and 1 or 2 columns apart, the same column and 1 or 2 rows apart or at a diagonal 1 or 2 wells part. C. Example of a plate exhibiting a star-like relationship between wells with overlapping BAC-end sequences.
