Umm - how does 'one' arrange a DNA (maybe blood?) test? It is difficult to go into details here without betraying confidential info..... but .... could/would a DNA test prove or disprove parentage? If it could/would - how do I set the process in motion? The possible half siblings are in agreement - the possible parents are all dead. We all think it would be nice to know! Help! Rosi. |

Without the parents, I am not sure it can be done. I used to work at a Solicitors in the family law department and when there was a query about the true parentage, both the child and the father had to have a blood test. I am not sure you can do it with just the child's blood. As for how to set it up, I guess they would just have to ask their Doctor??? |

Very interesting! have a look at this site it explains about "sibling tests" parents not needed. Doctors not needed. worth a read. http://www.genetic-identity(.)com/Sibling/sibling.htm Bob |

Rosi, here's a few I found that cover the UK The last one seems to be quite good as they send the kit out for you to take a sample at home and you post it back. http://www.easydna(.)co(.)uk/ http://www.londonbiosciences(.)co(.)uk/sibship.htm http://www.genetestlabs(.)co(.)uk/spedntst/siblingtest.htm http://www.proadn(.)com/en/dna_3 |

I know a parent and child test can 99% or more show definite parentage. I am sure that the percentage will be less, but am pretty certain a sibling test ( even half) will indicate a shared parentage - just not 99% |

Siblings need not technically share enough genetic information to confirm a relationship. Here's why: The egg contains half of your mum's DNA. The sperm contains half of your dad's DNA. Put them all together and you get one complete DNA package - you. A sibling also gets half your mother's DNA - but not necessarily the same half you did. You sibling also gets half your dad's DNA - but not necessarily the same half you did. For example, eye colour. Brown-eye genes are dominant, ie stronger than blue-eye genes. Let's say two brown-eyed parents have one brown-eyed baby and one blue-eyed baby. For arguement's sake, let's say the brown-eyed baby inherited one brown-eyed gene from mum and one from dad. But the blue-eyed baby must have inherited one blue-eyed gene from mum and another from dad. Going on this alone, the sibling DNA test would indicate that there was no link between the blood siblings. Parental DNA provides a much more accurate result. Obviously, professional DNA testing does not just rely on the gene for eye colour. But DIY gene kits are a lot less accurate, no matter what their manufacturers claim. |
