A list with elements:
A: Vector of unique alleles names. The allele numbers in the following quantities correspond to the indices of
G: 4-column matrix of unique genotype combinations. The presence of 0's indicates that less than four alleles were amplified indicating that a given genotype either has less than 4 distinct alleles or that some alleles are duplicated.
tab: Observed data in a simplified numerical format. This is a contingency table with rows given by the unique elements of
