Nucleotide differences within and between <i>Cerion</i> populations in the Florida Keys.

<p>Within population differences are shown on the diagonal, with the total number of nucleotide differences in the cytochrome C oxidase 1 gene (COI) (of 655 bp) above the line and the <b>total number of nucleotide differences in the 16S rDNA gene</b> (of 510 bp) below the line. Differences in the COI gene between populations are shown above the diagonal, <b>differences in the 16S rDNA gene</b> between populations are shown below the diagonal.
