Sorry, is it Y-Dna or Autosomal?

[@drmasroberts]

Because in the example of how the system works, the speaker only shows male names, and because he later talks about family names, it seems reasonable that he is talking about building trees from markers on the Y-chromosome.

The 111 marker test is Y-DNA.
