My boyfriends ex says that her daughter might be his or his fathers. Yea she slept with both. So if my boyfriend and his father take paternity tests will it show which one is really the father even tho they have the same DNA?
So whoevers DNA is higher percent is the father. So if my boyfriends DNA shows up like 99.3 % and his fathers shows up as 99.9% then his father is that babies dad?

I am sure it is heart breaking for father and child to find out 10-15 years later that the child they brought up is not theirs. Surely this should be done to allow partners of the mother not to be deceived into bringing up someone else's child.

The father of my daughter took a dna paternity test without me and the results were inconclusive. Now the lab has requested my boyfriend's father to come in and give a dna sample to clear this up.
The lab said that there was no problems with the sample. They said that the results were less than 85% and therefore need the paternal grandfather to come in for further testing. They also said that they looked at 15 different areas and tested the 15 areas 3 times and yielded the same response.

I want to know if many of the lie detector and paternity tests on the Maury,Steve Wilko, and various television talk shows are faked. For instance, I learned that a lie detector test is not very accurate in law enforcement. On the other hand, how reliable are these tests on these shows?

These days, DNA test are easy to get and considered very accurate. In the case where the identity of the father is in question, a DNA test is pretty much the definitive decision maker, and can have huge financial impacts when you consider things like child support.

However, I'm curious how paternity was legally established, for purposes of child support, before DNA testing was available?

I know how the paternity tests read (exclusion,inclusion) and all about the genetic markers, but how accurate is genetic testing. How possible is it for DNA testing to identify a man that is not the father as the father, or a man who is the father as not?

To Jetfighter for his comment- I know who my childs father is. I'm asking because some girls coming around saying shes pregnant with my little brothers baby and I was doing some research on paternity testing. Maybe next time you should keep your snide comments to yourself.

I've been reading up on paternity tests on the internet, and I saw a lot of ads for do-it-yourself paternity tests. How do they work? Do they send you a kit or something to collect samples with? Do they need a sample from you and the child, but not your partner? And how are they sure nothing happens to the samples along the way?
