Fig 6. Principal component analyses (PCA) of SNP data in DArT-seq alleles found in seven osteoglossiform species.

Fig 6

Individuals factor map using 3074 alleles (reference and alternative alleles). Osteoglossiform samples and presence/absence SNP were structured as observations (individual) and variable, respectively, as input matrix data. Notopteridae genera (Papyrocranus, Xenomystus, Notopterus and Chitala) and Arapamidae genera (Heterotis and Arapaima) together with their geographical distribution (Africa, Southeast Asia and South America); categorical variables are summarized in black (Africa), green (Southeast Asia) and red (South America) squares.
