Y-SNPs: Key to the future (Robert Casey)
Channel: Genetic Genealogy Ireland
Date: 18/11/2016

The explosion of Y-SNPs is having a major impact on Surname Projects. Robert explores how Y-SNPs can be used to determine when Y-STR matches are not actually related. Y-STR “signatures” are covered in depth and how these signatures can be used to determine relatedness and predict Y-SNPs which in turn reduces Y-SNP testing costs. The availability of this new and ever-increasing body of Y-DNA data now allows the creation of reasonably accurate genetic descendant charts by extending Y-STR signatures into the genealogical time frame.
