- A measure of the amount of homoplasy in a character relative to a given cladogram. The consistency index is calculated as the ratio of m, the minimum number of steps a character can exhibit on any cladogram, to s, the minimum number of steps the same character can exhibit on the cladogram in question. See also ensemble consistency index, retention index.
