Masatoshi Funabashi. Abstract—Genetic diversity in plant materials used for reveg-etation of disturbed sites is important to allow natural selection and adaptation to occur. Genetic Diversity Analysis. In addition to these inconsistencies, according to the allozyme results, geographic range and breeding system accounted for the largest proportion of genetic variation at the species and population levels, respectively [21]. The diversity of the metabolome in plants arises from genomic evolution, genetic diversity, developmental stages, and environmental stimuli. Similarly, this term encompasses various populations of one single species, like the different breeds of dogs or roses.
