Table 4.

A comparison of inbreeding statistics for the observed and each randomized pedigree: the average inbreeding coefficient, the number of nonzero inbreeding coefficients and the number of coefficients ≥ 0.125. For randomized pedigrees, the mean and standard deviation of the statistic over the 1000 runs of the pedigree simulation are given (no standard deviation is given for the observed value). Z test and P values are given for a one-tailed test of the hypothesis that the statistic is higher in the observed pedigree than expected from the distribution of statistics calculated from the simulated pedigrees. After a Bonferroni correction, the significance level for the tests in this table was taken as α = 0.003
