Phylogenetic Determination of Chenopodium quinoaBased on the Chloroplast Genes rbcL and matK

Figure 1

Nucleotide substitution rates (matK, rbcL, and matK + rbcL). The X-axis shows the substitution of one nucleotide for another during evolution. For example, AT implies a mutation in which adenine was replaced by thymine, and AC adenine was replaced by cytosine. The Y-axis shows the rate of substitution in the analyzed sequences.
