  1. N, Num, Eff_num, Hs and Ht. For each parameter is given the value (right) and the value with maximum likelihood-correction for polyploidy dosage (left). N: Sample size, Num: Number of alleles, Eff_num: Effective number of alleles (the number of equally frequent alleles it would take to achieve a given level of gene diversity), Hs: Heterozygosity within populations (polyploid lineages) or Gene diversity (the expected frequency of heterozygotes within subpopulations, assuming Hardy-Weinberg equilibrium), and Ht: Total Heterozygosity (The expected frequency of heterozygotes over all populations (polyploid lineages), assuming Hardy-Weinberg equilibrium). In brackets standard deviation is shown. In P. dioica, (*) means all the cytotypes 3x or 4x are included in the each group: (4x *4x, Mp 4x, 4x + Mp 4x; 3x *3x, Mp 3x, 3x + Mp 3x).
