Note.—“R” stands for “RNase.” For example, “R2/3” indicates the lineage of RNase2/3. Numbers in parentheses indicate the number of pseudogenes.
aThis group does not represent a monophyletic gene lineage, but it simply includes the species-specific genes identified in the opossum and the platypus that do not belong to any of the 13 ancient gene lineages (RNases 1–15).
