is it possible to do a bloodtest or what type of DNA test would be best in determining two supposed half sisters have the same father?
Hers is the scenario. My father is deceased! I have someone who states she jus fouund out many years later that my dad is also her dad.. (different mothers) . We want to prove whether she is or not my half sister, what is the best way to go abt this?

My granddaughter's dad was required to take a DNA swab when he was being sued for child support by the state.
We all went for the test & I witnessed the proceedure.However,when the results came back it was determined that not enough "viable"DNA was found to determine paternity & another was to be taken.
Alot of people told me he could have done several things to ruin the sample while still in his mouth.
He has been in prison & is knowlegable about many things like this.
For everyone's info,the weasel beat the child support order by getting on SSI!
There is no doubt he is my granddaughter's father,& there is no doubt he is a lying,lazy.,waste of skin the State is supporting now!

Im a teen parent and I was wondering how will I go about getting child support. The dad of course denys the baby, which is a typical thing, but I would like to also go about getting a dna test. Can someone please help because my baby is going on 2 and I would like her to at least know who her father is. Please help.

I'm pretty much convinced that my dad isn't my biological dad. We look nothing alike, have nothing in common, completely different personalities and body types. Everyone I know agrees with me. My mother lies so she wouldn't tell me who the real father is if she knew. I wanna get a dna test but I'm afraid of asking my dad. Can I just go to his house when he is out and get some hairs off his bed? Or would he need to go in person to take the test?

I am 22, and I have no idea who my dad is. Honestly, I really don't care anymore. I'm an adult, I went this long not knowing him, and I highly doubt I would even get along with him, given the men my mom has told me could be.
My problem is that my mom keeps calling me up, out of the blue, and telling me that she knows now. That I look just like this guy, or my eyes look like whoever. It changes almost monthly.
When I get my tax returns this year, I plan to end it once and for all, and get them all tested (5 people!)
Now, would it be morally wrong for me to also request a test on a man that died recently. His DNA has been saved, because they are still investigating his death. He is the one I most suspect to be my father.
The main reason I want to test all of them is just to make my mom stop all of this. If the dead guy is not my dad though, I'm afraid that it will make his family very angry that I am doing this... How should I go about it?
