Figure 2. PCR amplicons in the mitochondrial 12S and 16S rRNA genes from DNA samples, including a fly sample; commercial eel, shrimp, fish, chicken, pig, cow, and rabbit samples; mouse and human cells; 2 double-blinded (×1 and ×2) samples; and alligator, cat, deer, dog, donkey, duck, equine, pigeon, and turkey DNA.

The samples are respectively labeled as 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, and 21. M indicates the 100-bp DNA ladder.
