The distribution of mistyping probabilities for the markers in chromosome 7 is shown on the left, and the proportion of genotypes blanked on the right, as determined by the mistyping probability thresholds on the x-axis

In the Framingham data the four offspring in the third generation were assigned mother C, but the tests identified A as the biological mother
