DNA serves as a valuable solution for adoptees confronted with limited information in their records when initiating a search. Moreover, it is a useful tool for adoptees who have reunited with family and seek conclusive evidence of their biological connection.
In recent years, the utilization of commercial DNA databases for testing has witnessed a surge in popularity. These tests have been employed not only by those seeking ancestral lineage but also by individuals involved in solving police cold cases and, of course, by adoptees and donor offspring in pursuit of locating close familial matches.
While the introduction of a DNA testing program is indeed an exciting development, it is important to acknowledge the nuanced advantages and disadvantages associated with undergoing a DNA test through a commercial database. It is prudent to thoroughly assess the pros and cons before proceeding to order your test. Making an informed decision will empower you to navigate this aspect of your journey with clarity and confidence.

The concept of DNA testing is widely known, but understanding the specifics of what is being tested and how the results are obtained can offer deeper insights. The measurement of DNA length is quantified in centimorgans (cM). When all chromosomes are combined, the total DNA length amounts to approximately 7400 CM.
As an individual inherits half of their DNA from each parent, the shared DNA with each parent is typically around 3700 cM. Although minor variations can occur in the specific numbers for parent-child relationships, they remain relatively consistent. This serves as the basis for defining a parent-child connection.
Upon ordering a DNA test, a DNA kit is provided, along with instructions for the testing process. Before sending the kit back to FTDNA, it's essential to establish an account on their website and link the kit to this account. This account will serve as the platform where you receive your DNA results and discover your genetic matches. Familiarizing yourself with these steps will enable you to navigate the testing process effectively and access your results with ease.
