  • DNA Sibling Test

    This is a question for Max. A person who is interested in having her brother take the Y-DNA test for my Oliver group says that she and her brother took a "DNA Sibling Test" last year that proved that she and her brother have the same father. (No further infomation on the nature of the test was provided to me.) She asks if those test results can be used for the Oliver project. I suspect I know the answer but told her I'd ask anyway. If the answer is no, can you explain why?

    They undoubtedly used paternity testing (which is really a specific example of relationship testing). That uses markers on all the non-sex chromosomes, so their results would not be relevant for a surname project.
