Coefficient of Relationship

In population genetics, Sewall Wright's coefficient of relationship or coefficient of relatedness or relatedness or r is a measure for the level of consanguinity between two given individuals.

The coefficient of inbreeding is calculated for a single individual, and is a measure for the amount of pedigree collapse within that individual's genealogy.

Roughly speaking, the coefficient of relationship approaches a value of 1 for individuals from a completely inbred population, and approaches a value of 0 for individuals with arbitrarily remote common ancestors.
