  • Total numbers of alleles in common, markers in common, number of alleles with extreme residuals (see text), and number of markers that had alleles with extreme residuals, broken down by base-pair repeat type of the marker.

  • Here we count the number of times an allele in one data set matched with more than one other allele in the other data set.
