BROTHER TO BROTHER DNA TEST

There are two major testing options for brother to brother tests.

1. Y-chromosome testing. €299 for 2 persons (€99 for each extra person)

Y chromosome DNA testing - Brothers testing for the same father
  • Y chromosome testing is used to see if two or more male persons have the same biological father. If you also (or only) wish to know if they have the same Mother, then you will require a Full Sibling to Sibling Test.
  • Y-chromosome testing is your least expensive option while obtaining very high accuracy (99.9%+).
  • All men have one Y chromosome, it is passed down from Father to Son, woman have no Y-chromosome DNA. Therefore a Father and his 3 sons will all have the SAME Y-chromosome DNA

2. Full Sibling to Sibling testing. €495 for 3 persons (€99 for each extra person)

  • If perhaps the 2 or more brothers that you want tested have different fathers that could be related, or if you want to know if the persons being tested have the same Mother, then you require a Full Sibling to Sibling Test.
  • This test investigates a high number of DNA regions. Full or half siblings will differ in the amount of DNA that they share. A Full Sibling to Sibling test looks at so many pieces of your DNA that we can make an assessment of your relationship.
  • To have the Mother's DNA sample (from both or either brother) drastically increases the accuracy of the test.
