Interpreting DNA
May 16, 2018
Hello, I would like some assistance in relation to understanding DNA matches. I have a Sicilian background. My DNA result says I have 60% Greek and 15% Sardinian links. My cousin, also of Sicilian background, was tested from the Ancestry site. His results showed 71% Sicilian/Southern Italian links and 0% Greek link. My Heritage has no Sicilian/Southern Italian category and Ancestry has no Sardinian category. Is someone able to explain why this may be the case or guide me to a resource which explains boundaries/categories of DNA matches and how and/or why they may differ between different companies? Thank you for your time, Joe.
