The other day my sister was watching some crime show where the cops used cum which had been left on the table of a crime scene and pulled the DNA from it. This made me wonder how realistic this is. I know that cum inside the body can survive a while. But if you just jizzed on a table, how quickly would a scientist need to get their hands on it before it was totally unusable for DNA testing
>>
there's a big difference between the swimmers still being alive and the dna mallahcuuls being intact enough to id

>How identifiable is cum when left outside the human body for a while?
>DNA from 120,000yr old teeth and from residue of living things in 100million yr old amber can be recovered
DNA is quite robust.
Bloodstains for instance last 300yrs.

I bet you could identify it by taste

>>16830735
Makes sense, thanks. So I guess you could ID a suspect even with really old sperm?
>>
come on op you can tell us, what have you done?
>>
>>16830975
I have done nothing. But I do have fantasies of jerking off in public. I was curious about how bad it would be not to clean up after
>>
>>16830759
yeah people are digging Denisovan and Neander DNA out of 200000 year old remains

I can assure you that the old cum you found on your sister's panties is either yours or your dad's. 50/50.
