Figure 3.

Phylogenetic network of pale flax and cultivated flax at the sad2 locus. Eleven nodes reflecting 11 haplotypes detected across 113 samples were labeled from I to XI. Labels within a node relate to accessions (see Table 1). The size of node circles relates to sample frequency. The numbers by branches indicate the positions of substitutions detected for that branch. Character conflicts are described as reticulations within the network. The position of the most likely domestication common ancestor (DCA) to all alleles in cultivated flax is indicated by DCA. Five recombination events were detected and numerically labeled.
