Half-sisters into Ancestry DNA
Half-sisters for the Origins DNA arise once the “Close Friends” otherwise “Earliest Cousins” as they are anticipated to express on average step 1,759 centimorgans which have various 1,160-2,436 centimorgans, according to research regarding the Mutual Centimorgan Opportunity.
On this page, I shall take you step-by-step through new particulars of the outcomes of half-siblings, just how much DNA they express, how appropriate the exam try, and much more. This post will help you to know your test results, in addition to techniques general.
