mixing autosomal DNA test results and Y-DNA test results
A comment about mixing autosomal DNA test results and Y-DNA test results.
One person can match their autosomal DNA test results with a second person's autosomal DNA test results and then reference that second person's Y-DNA test results (if the paper-trail supports a common line there) but a person cannot jump directly from their own autosomal DNA test results to a second person's Y-DNA test results.You can't skip that middle step of matching the autosomal DNA test results.
