From: Modelling the correlation between the activities of adjacent genes in drosophila
Pearson R for non-adjacent genes in the adult flies, compared to a mixed fly group of the same size (54 flies). The average correlation is the same in both fly groups, but strong positive and negative correlation occurs in the mixed group. This is consistent with the assumption that strong correlation of two genes can occur when both genes are upregulated (or downregulated) in one age group relative to the other age group.
