Does earwax contain DNA?

While not all these bodily substances provide ideal DNA samples, testable DNA can often be extracted from all of them. In every case, what is being tested is the DNA contained in cells of human tissue, whether found on their own or carried by another substance, like earwax, sweat or mucus.

Can you get DNA from vomit?

Gathering DNA Evidence

DNA testing has expanded the types of useful biological evidence. All biological evidence found at crime scenes can be subjected to DNA testing. Samples such as feces and vomit can be tested, but may not be routinely accepted by laboratories for testing.

Why is earwax sticky?

Wet earwax has a lot more lipids, which make it thick and sticky. It is most common in people of European and African descent. Dry earwax is flaky and is most common in Eastern Asian populations. The variant of the ABCC11 gene in your DNA determines whether you have wet or dry earwax.
