Table 2 Increased technical replication leads to an increased power to detect array features that show a difference in the hybridization strength for D. yakuba vs. D. melanogaster

# Arrays # Analyzed Diverged ID-50 R2(%ID/Hyb)
2 15372 61% 92.8 0.4085
4 15851 75% 95.0 0.4382
6 16001 80% 95.7 0.4485
8 16060 83% 96.0 0.4530
  1. # Analyzed: a reduced dataset due to removal of features on the X chromosome; Diverged: percent of features identified as diverged at P < 0.1 FDR; ID-50: %ID at which there is a 50% chance of a feature being identified as diverged; R2 (%ID/Hyb): R2 for the regression of %ID on hybridization ratio.
