con·cor·dance rate

the proportion of a random sample of pairs that are concordant for a trait of interest. A high rate of concordance may be generated in several ways, many of which may result from irrelevant bias; but broadly it is taken as evidence of causal connection (for example, in the case of identical twins, a genetic component or in spouses of assortative mating).

concordance rate

n.
A quantitative statistical expression for the concordance of a given trait, especially in pairs of twins in genetic studies.

con·cor·dance rate

(kŏn-kōr'dăns rāt)
The rate of occurrence of a trait, behavior, or action in members of a specified group as compared with the occurrence of a trait of interest. Broadly, it is taken as evidence of causal connection.

concordance rate

The frequency with which a gene will be inherited or expressed by identical or fraternal twins.
