  1. Inaudible for me as well and my volume control it all the way to the max. Also, autosomal tests DO include both maternal and paternal lines.

  2. sue lane says:

    I am a bit confused. I thought that both the Maternal and Paternal sides are reflected in the Autosomal testing. However it is the direct Maternal and Paternal lines which are traced respectively from the Mitochondria and Y Chromosome. (Both sexes have Mitochondria but normally only males have the Y Chromosome.)

    Also, I assumed that the genes are not tested for genealogical purposes. That makes sense as genes are subject to selection which can skew the results.

    So the 700,000 SNPs (Single Nucleotide Polymorphisms) Ancestry test ought to be on the non-coding regions of DNA. (SNPs can be found anywhere in the genome.)

    Again it would be the non-coding areas for the Y chromosome. They also use STRs (Short Tandem Repeats) as this type of mutation happens quicker than the SNPs and can be correlated to the Surname lineage in Countries where that is Paternally inherited.

    Of course 23 and Me do test Gene Alleles for physical characteristics. I do wish they would name any Neanderthal genes tested rather than just the percentage!

  3. Very low volume, but thank you for the demonstration.

  4. Again, we are sorry it isn't working for you. You might check to see if that video is muted on the screen (to the right of the play button) or to see if you have volume keys on your keyboard that might be muted or very low. We have tried several computers and are able to get sound on all of them.

  5. Bro Dunn, your presentation says that autosomal tests are for "all lines except paternal." Yet on FamilyTreeDNA, it says: "Autosomal DNA is DNA from one of our chromosomes located in the cell nucleus. It generally excludes the sex chromosomes. Humans have 22 pairs of autosomal chromosomes and one pair of sex chromosomes. You inherited your Autosomal DNA from both of your parents, all four grandparents, all eight great-grandparents, etc. This is why Family Finder results generally include matches from all of your lines." Which is right? Do my autosomal test results include data from my paternal line?
