Response of (a) Observed Heterozygosity (ho), b difference of expected minus observed heterozygosity (he - ho), c number of Diagnostic Markers (markers fixed only for a small number of genotypes in the sample, ndiag), and d. proportion of missing values in the sample (pmiss), for six sample sizes (0, 5, 10, 20, 30, 40 and 50% of the size of the whole collection), two types of samples (independent: i, and nested: n), and two strategies for selecting the best sample (Core Hunter: CH and D-method: DM). The response is expressed as the quotient (sample value) / (collection value) (red horizontal line). Blue lines represent different sized intervals of the distance from the collection value
