a
Number of genes that can be accurately assigned into these two events based on Ks values; numbers in parentheses depict the number of families these genes were clustered into.
b
Rho, the Spearman’s rank correlation coefficient between the copy number of retrogenes and their expression levels (RPKM) as recently measured for genes in each family (Lin etal. 2015).
