COI haplotype (TCS) network showing the relationships <i>A</i>. <i>anatina</i> haplotypes.

<p>Colour codes correspond to the 5 haplogroups: Blue—Northwest Iberia; Green—Southcentral Iberia; Red Southwest Iberia; Purple—Europe; Yellow—Western Mediterranean. Within the European haplogroup, Russian haplotypes are represented in dark purple and Ukrainian in light purple. Circle size is proportional to the observed haplotype frequencies, white dots represent unobserved haplotypes.
