Average degree of separation between kinship categories achieved by the Loiselle kinship estimator \(\left\langle s \right\rangle\). The dependence of \(\left\langle s \right\rangle\) on the value of \(D_{1}\) in family A (a) and family B (c) and the dependence of the same quantity on the value of \(D_{2}\) in family A (b) and family B (d). Random ensemble is represented by the gray area defined from above by maximum values of \(s\) and from below by minimum values of \(\left\langle s \right\rangle\)
