Unsupervised grouping of Triticum aestivum subsequences by progenitor of origin using repeat-k-mers. a PCA labeled by database-free grouping of 250 kb genome segments by polyCRACKER (Subgenomes a, d and ss are colored green, blue, and red respectively). b Spectral embedding of Triticum aestivum dimensionality reduced information (reduction to 4-dimensions, visualized in 3-dimensions), in which edges (grey lines) represent shared repeat-mer profiles that connect genome sequences. c Database-free grouping of a and d subgenomes by polyCRACKER, and (d) sequences colored by their similarity to T. urartu (green) and A. tauschii (blue)
