If you, or someone you know, is living in a house where you and your siblings think that you are related as half siblings,
but do not know for a fact, then maybe it is time to do a half sibling DNA testing. One might consider doing DNA testing half siblingship because they were raised by adopted parents and know who their mother is but are not certain of who their father is.
Or perhaps you know who your mother is, and she told you who your father is, but he has died, and the only way to see if you are a part of this other family is through half sibling DNA testing. The reasons to do half sibling DNA testing are larger than one might suspect.
While doing DNA testing for genealogy of DNA testing half brother and sister is not as accurate a test as doing grandparent DNA testing, since siblings take different parts of their parent’s DNA, so if you do DNA testing half brother and sister without a DNA sample of at least the mothers (to know where at least half of each of your DNA has come from), the results of half sibling DNA testing is accurate, but not as accurate as maternal or paternal DNA tests.
Normally, finding one’s birth mother is a much easier endeavor if you have been adopted. Nearly all adoption agencies have the birth mother’s name (if nothing else), and nowadays, these records are not confidential as they were in the past. But often (but clearly not always), when women decide to give a baby up for adoption, it is often because the man that impregnated them does not want to be involved in raising the baby. So, although doing DNA testing history is often hard to come by, DNA testing half siblingship is sometimes more possible.
More and more children that were adopted have begun the search to find their birth parents, often when they are adults and can afford to buy the expensive sibling DNA testing and to do half sibling DNA testing.
Half sibling DNA testing is not actually so expensive if the DNA testing half brother and sister turns out to be a match after the first test. But if you have to buy several DNA testing half siblingship kits, then it will obviously add up. That is why it is always recommended to really do your research before embarking on half sibling DNA testing. See all of the links to DNA testing half siblingship on this page for more information.
