Using principle component analysis to compare genetic diversity across polyploidy levels within plant complexes: an example from British Restharrows (Ononis spinosa and Ononis repens).

Abstract excerpt

The investigation of genetic diversity between related plant populations which differ in ploidy levels is problematic, with common statistical methods developed for diploids being inappropriate for polyploid species. Studies into gene flow in such complexes are critical and can shed light on the mechanisms that generate and maintain populations of different polyploidy levels. We have investigated the use of...
