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
>>16830733>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 recoveredDNA is quite robust.Bloodstains for instance last 300yrs.
>>16830733I bet you could identify it by taste
>>16830735Makes 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?
>>16830975I 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
>>16830759yeah people are digging Denisovan and Neander DNA out of 200000 year old remains
>>16830925I can assure you that the old cum you found on your sister's panties is either yours or your dad's. 50/50.
