Without a chromosome browser and access to shared DNA segment data, customers of Ancestry.com's autosomal DNA genealogy product, AncestryDNA, cannot positively identify the ancestors responsible for the DNA shared with each genetic relative. Without access to and analytic tools for shared DNA segment data, AncestryDNA customers routinely draw inaccurate conclusions about their pedigrees and how they relate to each of their reported DNA matches. In the absence of matching segment data, AncestryDNA's Shared Ancestor Hints, a feature that pinpoints a set of common ancestors in each match's family tree, can mislead and has misled countless Ancestry customers seeking to solve genealogical problems with genetic testing. Continuing to sell AncestryDNA without a chromosome browser and shared segment data, essential features of any autosomal DNA genealogy product, minimizes the product's accuracy, utility, and integrity as a resource for genealogists and does a disservice to a community of customers who have supported Ancestry.com for all of its 17 years.
