From: Genome assembly and population analysis of tetraploid marama bean reveal two distinct genome types
Population analysis of 31 T. esculentum samples reveals two distinct clusters. (A) Principal Component Analysis (PCA) plot of the first two principal components. Each dot represents one sample, colored by its sampling location. (B) Map showing sampling locations across Namibia, South Africa, and surrounding countries, with dot colors matching Panel (A) and sizes indicating sampling size. (C) Unrooted maximum likelihood (ML) tree constructed from a PHYLIP alignment of 23,772 SNPs, depicting the relationships among the 31 marama samples. (D) ADMIXTURE analysis of population structure at the optimal cluster number, K = 2.
