Summary

The decomposition of the total gene diversity in a substructured population into its components is presented when the sizes on the subpopulations are not necessarily equal. The effect of unequal subpopulation sizes on the coefficient of gene diversity is also discussed. The sampling variance of this index of subdivision, derived here, can be used to measure the extent of the effect of subdivision more objectively.

Zusammenfassung

Die Untergliederung der gesamten genetischen Verschiedenheit in einer substrukturierten Population in ihre Komponenten wird dargestellt für den Fall, daß die Subpopulationen nicht notwendig gleich groß sind. Die Auswirkung ungleicher Größen der Subpopulationen auf den Koeffizienten der genetischen Verschiedenheit wird diskutiert. Die Stichproben-Varianz dieses Index der Unterteilung wird abgeleitet; sie kann helfen, das Ausmaß des Effektes der Unterteilung objektiver zu messen.
