-
↵a Breadth of expression was averaged over experiments in human and mouse for the human—mouse comparison, and was obtained from mouse only in the mouse—rat comparison. Only nondisparate gene pairs were included.
-
↵b Pall is the fraction of equal or greater ρ in datasets obtained by randomly permuting all genes.
-
↵c Pgroup is the fraction of equal or greater ρ in datasets obtained by randomly permuting genes within classes of similar K4.
