Fig. 2From: Genetic variation and population structure of clonal Zingiber zerumbet at a fine geographic scale: a comparison with two closely related selfing and outcrossing Zingiber speciesGenetic-group-structure shown by STRUCTURE analysis for local populations of Zingiber zerumbet within the microgeographic area. Each individual vertical bar represents an individual and the black vertical bars separate the local populations, while different colors represent different gene poolsBack to article page
