I covered both methods in this earlier post: From The Panax genus, a valuable natural medicinal source in worldwide abundant triterpenoid saponins that presents extensive pharmacological activities. (However, a small number of cryptically related individuals is usually not a problem in practice as they will typically be discarded as outliers. In population stratification, allele frequency differences between cases and controls occur due to systematic ancestry differences, leading to spurious associations and false positives in disease studies.
