  1. Sampling method (method) and sample size: proportion of missing values (pmiss), expected and observed heterozygosity (he, ho), entropy Shannon index (shan), Modified Rogers’ distance (mrd), number of retained markers (npoly), and number of markers fixed for only a few accessions (ndiag). Ratio is equal to 1.0 if sample measure is equal to population measure
  2. aCHi Core Hunter, independent sample, CHn Core Hunter, nested sample, DMi D-method, independent sample, DMn D-method, nested sample, SE minimum and maximum standard error of mean
