There is a good website (and book) by Chris Pomery that compares the various genetic testing facilities. Sadly, there don't appear to be any free facilities. Follow the link below and scroll down. The various companies are listed at the top of the coloured table with links to their websites. You might be able to ask them directly for further information.
No, I know mine are related to me, my older sis and I look too much alike to not be sisters and my brother and I are too much alike sometimes. They may wish they could dna test me away, but they can't. Hehe.
I have found the woman I believe to be my half sister. We are considering taking a DNA test to see-however, the father we share is not available. Is blood better than buccal for the test? Are we likely to get false indicators? How do I know the company is reputable?
Blood or buccal either way, you are going to get the same results. You also do not have to have the father available for testing to find out if you share the same DNA with this other woman. It just is not necessary. If you are concerned about the reputation of the company then I would suggest checking with the Better Business Bureau (if in the USA), or a local hospital would be able to give you information on how to find the reputability of a particular company.
Is it possible tu use DNA test to determine if 2 siblings come from the same father?
We just found out my father has another kid with a gold digger he met some time ago, and it doesn't really look like him.
Me and my sisters are wondering if its possible to make and DNA test between any of us and the kid.
We don't want my dad find out about it.
Can a DNA test between siblings tell if they have the same Father?
I was adopted when I was 15 months old, I have always known my biological Mother. At the age of eight, my friends Father told me he was my Dad, But my mother has totally denied this. The man treated me very good. Some years ago he passed away still saying I was his child, I was put into his obituary along with my children as his grandchildren. The man I am married to now turned out to be this mans relative, if he was my Father we would be cousins. Would a DNA test between us children tell me the truth?
Can DNA tests prove if siblings have the same parents if one parent is deceased?
I am not that familiar with DNA testing, but if I found my brother could we be tested to see if we shared parents and if so how is that determined? but if you only take DNA from one parent it will prove that you are siblings but not that you share parents. Right? So how could they determine if you share parents?
Yes! they will take samples of your living parent, from you and your brother. they may even take samples of the paternal grandparent (s) too, but most likely they will just use the three of you.
how can they figure it out? simple- they match the genetic code- your moms (in both of you) then they will isolate the remaining markers to see if they match. the higher the number of markers you share (aside from the ones from your mom) the more chance it is you share the same father.
