Intermediate and Advanced Y-DNA Topics - Beyond STRs

Brad Larkin’s presentation offers a deeper understanding of Y-DNA Next Generation SNP genetic genealogy tests like the Big Y-700 and YSeq's whole genome sequencing. He journeys from biology, to data, to the phylogenetic tree, and finally to geographic interpretation. Topics include: explanation of raw read alignment to the genome which produces your SNP results; understanding your terminal SNP and why it changes; how to use novel variants and unnamed variants to extend the phylogenetic tree for your family; and tips on getting the most information and avoiding bugs in current tools using real world examples.
