针对被收养者的亲子鉴定和寻亲

是的，可以！个人基因检测为您提供了找到有关您家庭相关信息的最佳机会。常染色体 DNA 测试还包括您的种族血统细分，这可能会很有趣。

许多被收养者已通过基因检测和其他可用资源成功找到了亲生父母。然而，基因检测对于族谱学问题也很有帮助。许多人已成功使用 Y-DNA 结合 atDNA 和历史记录来识别非婚生祖先的父亲。其他人使用 atDNA 以克服近期的族谱学难题。还有些人使用 mtDNA 来支持他们与共同母系祖先的血缘关系，或确认或反驳关于非洲或美洲原住民血统的家族传说。

• Don’t delay! As genetic testing databases grow, more adoptees are getting a direct match with a parent, sibling, aunt, uncle or close cousin, allowing them to complete their search with little additional effort. Most adoptees will uncover some distant cousins of varying degrees. Working your way from their ancestors to recent relatives will require additional time and effort.
• Get yourself into multiple autosomal DNA databases. This will give you greater chances at high ranking results. Each service may identify people with whom you share a common ancestor somewhere in your family trees. While your family tree may still be blank, many of your genetic matches will be amature genealogists with extensive family trees.
• If you are male, take a Y-DNA test. Only men have a Y chromosome, which they get from their biological father who got it from his father and so on. Surnames typically pass down this same paternal line. So a man’s closest or most frequent matches on a Y-DNA test may share the same last name as his biological father.
• Skip Mitochondrial DNA testing. Everyone has mitochondrial DNA (mtDNA). Only women pass on mtDNA, so the test only traces your direct maternal line. Unfortunately, most of your mtDNA matches reflect common ancestors from hundreds of years ago. With female surnames changing every generation, this test is rarely helpful for adoptees.
• Know that geography can impact results. Choose a company with a global database and a diverse family tree collection, such as MyHeritage. Those born outside the US or those with a recent immigrant background from Asia, Africa, and Eastern Europe, have a better chance of matches with MyHeritage DNA.
• Educate yourself and get help online. Start reading up on DNA testing for adoptees and join DNA discussion groups on Facebook and other forums. Advice from others can really help with your own personal research.
• Use the right tests to confirm relationships. Once you find someone from your birth family, there is often a need to confirm the relationship. Some autosomal DNA tests are powerful enough to confirm several close relationships between two people, such as parent-child, full siblings, half siblings, aunt/uncle with nephew/niece, grandparent-grandchild, first cousins and usually second cousins.

Personal genetic DNA testing has revolutionized the process for adoptees of finding biological family. It is simple and painless to take a personal MyHeritage DNA test. Just brush the inside of your cheek with a swab, and send your sample into the lab. Within 4-6 weeks, your results will be available online at MyHeritage.
