Figure 1

Example of an identification procedure for CNV gain or loss status. Y axis represents log2ratios and X axis represents genomic positions along chromosome 7. (A) animals 2 vs. 19; (B) 19 vs. 6 (gain in 19 or loss in 6); (C) 6 vs. 20 (loss in 6 or gain in 20) and (D) 20 vs. 17. The only plots that show a CNV are B and C, and since the only animal common to those hybridizations is animal 6, we classify this CNV as a deletion in animal 6.
