Figure 4. Fragment recruitment heat maps for each sequence dataset based on sequence identity alignment of individual reads to the relevant mitochondrial genome sequence.

A–digestive gland; B–foot; C–gill; D–mantle. Purple regions are ribosomal RNA genes and blue regions are potential tRNA sites, white regions are coding sequences; CYTB–cytochrome B, COX2–cytochrome oxidase subunit 2; ND1–NADH dehydrogenase subunit 1; ND4–NADH dehydrogenase subunit 4; COX 3–cytochrome oxidase subunit 3; ND2–NADH dehydrogenase subunit 2; ND3–NADH dehydrogenase subunit 3; COX1–cytochrome oxidase subunit 1; ATP6–ATP synthase subunit 6; ND4L–NADH dehydrogenase subunit 4L; ND5 - NADH dehydrogenase subunit 5; ND6–NADH dehydrogenase subunit 6.
