By "types," I mean several different species of animals. If, post extraction, the pure, isolated DNA of several different animals were mixed together and run through DNA analysis, I know the results would be inconclusive, but would there be any usable information returned at all? Would any species be individually identifiable?
The scenario is hypothetical and for a TTRPG plot; the players procured samples of a substance that they don't yet know are isolated DNA polymers (think the "extracting strawberry DNA" science experiment for children) from several different species of animals and a couple of humans, which was mixed together post-extraction. They'd like to have the DNA samples analyzed. Handwaving turnaround time (I know this process would realistically take weeks to months at the bare minimum, but if crime procedurals can deus-ex analysis results in 48 hours, so can my players), what would that analysis turn up?
Would they be able to parse specific species, or the ratio of one species to another (ie the sample only containing one or two dogs, but many, many small birds and squirrels)? They almost certainly wouldn't be able to turn up any kind of identifiable information on the human DNA, even with an uncontaminated reference sample, right?
