Quizplus · Accepted Answer

The coefficient of relatedness (r) quantifies the average proportion of genes shared by common descent between two individuals. It is used to predict the genetic similarity between the actor (the individual performing an action) and the recipients (those affected by the action), rather than the maximum degree, the probability of sharing any random genetic trait, or membership in the same species.
