Figure 8.—

Mean estimates for the CEPH data set, based on the first set of 49 loci. The families are denoted as follows: U₁, …, U₆ refer to Utah families 1331, 1332, 1347, 1362, 1413, and 1416; A refers to the Old Order Amish family 884; V refers to the Venezuelan family 102. For each family, we have plotted the mean estimates in two columns: The left column has the MLE estimates calculated with θ = 0.0, 0.01, 0.02, 0.03, 0.05. All MLEs are indicated by solid circles, with darker shaded circles indicating lower values of θ. The right column has the other estimators with symbols as follows: ▵, Queller–Goodnight; +, Lynch–Ritland; x, similarity index; ⋄, Wang. Above the horizontal axis are values indicating the number of relative pairs evaluated in each family.
