Figure 3. The partial alignment sequences for the PCR amplicons of the mitochondrial 12S rRNA (Figure 2a) and 16S rRNA (Figure 2b) genes from 9 animal species, including the fly and 2 double-blinded samples (×1 and ×2).

The locations of the universal primers were located in the 12S and 16S rRNA forward and reverse sequences and are marked with colored bars.
