False classification rates. False classification rate for subsamples of markers for the Bluestone Pond (a) and Toro Pond (b) tiger salamander data peaked at 10 markers when the typical six category system (limited to parental, F1, F2, and backcross genotypes) could be rejected by the MLE of S and H
. Shaded symbols show results for classification based on 2 log-likelihood units; black symbols show results for the AIC criterion. However, with a priori limitation to the six categories (open symbols), large numbers of markers invariably lead to a single confident classification for all individuals in the dataset. Points illustrate medians and bars the 0.25 to 0.75 interquartile range (covering 50% of the subsampled data sets for each number of markers). False classification rates specifically for F1 and parental categories (c and d) decline with the number of markers.
