Glossary of "Cladistics (2nd ed.)" by Kitching et al. (1998)
- A component is replicated on two cladograms if it is present in both, irrespective of the internal relationships of its constituent taxa. Thus, if one cladogram includes the clade A(B(CD)) and another cladogram includes the clade A(D(BC)), then the component (BCD) is replicated in both topologies.
