Will dna anncestry prove we are full sisters?

[Scorpion84]

I don't want to go into lots of details as it's outing but essentially my 3 siblings think I have a different dad

I'm extremely confident this isn't the case as I have dna matched with a very distant cousin but this is on my dads side of the family through confirmed with relatives on his side

I have told my siblings this but they don't seem to take this on board .

dna tests are expensive so I was thinking if I upload my sisters dna ( with her permission) will this show we are full siblings if we are ? As does dna anncesty differentiate between full and half siblings ?

You can tell the difference between full and half siblings by DNA testing.

But why are your siblings being so mean to you? You shouldn't have to justify your existence to them. What does your mother say? They are accusing her of having an affair.

yes and this has been going on since I was a teenager I'm now 40.

ive asked my mom she said there's no way i have a different father . I also asked my dad when he was alive and he told me I was definitely is .

I really don't know why they have this question mark against me . I've buried this for a long time but I feel I have to prove it to them

Are they still mentioning this after all these years?

@BunnyRuddington yes to the point a few years ago my brother offered to pay for a dna tests so I can have answers !

they are the ones with questions not me .

they seem to hate my mother . We didn't have a great childhood but it wasn't all my moms fault .

Yes.It will show centimorgans & match you, you can compare DNA percentages to establish full or half siblings but yes, how mean of them. I'd be very pissed off with them but a small part of me would be curious.

I want to prove them wrong. I don't doubt my dad is my dad but I feel this is the only way to prove it

Discuss it again with your mother before you do it.

@Redrosesposies mom said it's a waste of money but she understands why I want to do it .

Why not let him pay for DNA tests then?

@NotSafeInTaxis

I don't have any contact with him or my other brother . I still have a relationship with my sister .

husband said I should get him to pay but I don't want to contact him .

Basically this has been going on for years and it's not going to go away unless I have some kind of dna tests .

Im Just really angry that this was said to me when I was 17 without any real foundation .

I would listen to the podcast The Gift on BBC Sounds before embarking on this.

Your Dad is dead and he loved you. Even if he wasn't your father biologically he's still the man who loved you and raised you. I don't know if your siblings think or know that you have a different father but you have two choices:

Firstly, whenever they raise it shut down the conversation down by telling them that as far as you are concerned the genetics is irrelevant, your Dad raised you and cared for you and he is and will always be your Dad and you find it very upsetting that they persist in emphasising genetics over that. If they ask about tests refuse. Don't let them bully you.

Secondly, you do the test so you all have clarity. But agree with the PP, speak seriously with your Mum about it before agreeing to do it, tell her as far as you are concerned your Dad will always be your Dad but your siblings keep on insisting he is not so you want to do a DNA test to prove to them that he is genetically your father and if that test is going to throw up any unexpected results you'd like to be forewarned because that would change your decision to do the test because you don't want to give your siblings concrete reasons to treat you like shit. If your Dad isn't your biological father it might be for reasons that your Mum and Dad wanted to keep private so it's not just about what you and your siblings think.

Am I right in thinking there's no way I can match with someone on my dads side of the family however distant without being related genetically?

Thing is, if your brother is as fixated on this as it sounds, he could claim your biological father is your dad's brother/cousin/guinea pig rather than just accepting he is wrong.

@OminousFlute yes I agree .

That is correct, but that doesn't necessarily imply that your dad must be your biological father.

It could also be some other male relative of his that is your biological father. Perhaps a brother or male cousin of his?

I don’t think so but it means that apart from your dad, another blood linked relative could be your father instead. If you uploaded your sis’s dna it should show you are full siblings …but obviously there’s some weird family dynamics going on over this.

You could share a common ancestor between your mother & father generations back which could account for the distant cousin.

If you do a test and you are full siblings with your sister, your brother could just say that the two sisters have a different father to him. The only way to be sure you are all full siblings would be for all of you to be tested.

if you have no contact with your brothers there is probably a reason beyond this comment about parentage made decades ago. Why not just accept that you know who your parents are and that your brother is toxic and best ignored. It can’t come up very often if you are no contact with him.

Just have the tests then never contact them again.. At least you will have peace of mind he is your df.. And peace from those nasty people..

Is her question eg an inheritance related question?

Do you like her? I suspect not. Do you have to maintain a friendly relationship now you’re adults? I suspect not.

You’ve done your bit. She can do her bit, she just doesn’t want to for unknown, mysterious, nasty reasons that are over two decades old. Because how can she continue to say what she says if there’s DNA evidence?

Be like your brothers! Bin ‘em all off (except your mum?) and live your life! 😆

Just to clarify my eldest brother started this when I was 17 . He clearly told my other brother and my sister . Sister is younger than me and her parentage has never been questioned . Because I don't look like them , I follow my moms side of the family very much

there's a big age gap between me and my brothers so I I've wondered what did they see? Did they see my mom with another man ? I've asked them both this and they haven't so I really don't know evidence they have for burdening me with this for so many years .

we did have regular contact until my Nan died 13 years ago .

we did inherit from dad a small amount he has been dead for 20 years .

I'm sorry girl, no advice, but it sounds like they're being quite cruel 🥺 - could you just do a dna test to put it all to bed? 💕💕

Edit, maybe ask your brothers to pitch in, put their money where their mouths are x

OP has done a test. It’s in her first post.
