The field of genetic genealogy has grown exponentially over the past few years as testing has become more accessible, popular and affordable.<\/p>\n<p><a href=\"https:\/\/www.familytreedna.com\">FamilyTreeDNA<\/a> was the first company to develop and deliver the commercial application of DNA testing for genealogical purposes, previously available only for academic and scientific research.\u00a0 Taking one of our DNA tests gives individuals the means to check and compare their discoveries with other testers\u2019 data in the world\u2019s most comprehensive DNA matching database.<\/p>\n<h2><strong>Our Genetic Ancestry Is Written Into Our DNA<\/strong><\/h2>\n<p>Biologically speaking, we are who we are because of our <strong>DNA<\/strong> short for <em>deoxyribonucleic acid<\/em>, the beautifully intricate genetic code inside every cell containing vital information about all living beings. It is the molecular \u2018blueprint\u2019 of life etched within our cells and passed down from generation to generation.<\/p>\n<h2>DNA: Your Genetic Code<\/h2>\n<p>Humans are made up of trillions of cells, most of which contain a copy of your DNA, a complex molecule consisting of your genetic code, a combination of DNA from each of your parents. DNA carries your biological instructions, the encyclopedia of where you come from, and the story of your ancestors as told through the bits of DNA passed down to you.&lt;<\/p>\n<h2>DNA for Ancestry and Family History<\/h2>\n<p>There are three major types of genealogical DNA tests: <strong><a href=\"https:\/\/www.familytreedna.com\/products\/family-finder\" target=\"_blank\" rel=\"noopener\">autosomal DNA<\/a><\/strong>, <strong><a href=\"https:\/\/www.familytreedna.com\/products\/y-dna\" target=\"_blank\" rel=\"noopener\">Y-DNA<\/a><\/strong>, <strong><a href=\"https:\/\/www.familytreedna.com\/products\/mt-dna\" target=\"_blank\" rel=\"noopener\">mtDNA<\/a><\/strong>. However, there are differences in the way the various types of DNA are passed down from generation to generation:<\/p>\n<h3>Autosomal DNA<\/h3>\n<p>An autosomal DNA test examines the 22 out of 23 pairs of chromosomes in your DNA. Most of the hereditary information is on the 23rd pair (a combination of X or Y) also known as the sex chromosomes.<\/p>\n<p>Because these 22 pairs of chromosomes, called <em>autosomes<\/em>, are inherited from both parents (and all recent ancestors), a parent and a son or daughter would share roughly half of their autosomal DNA.<\/p>\n<h3>Y-DNA<\/h3>\n<p>Y-DNA looks at the Y chromosome which is inherited solely from father to son. As such, Y\u2013DNA tests can only be taken by males to explore their direct paternal line.<\/p>\n<h3>mtDNA<\/h3>\n<p>While both males and females inherit mitochondrial DNA (mtDNA), only biological females can continue to pass on mtDNA. mtDNA testing can help you discover and verify your direct maternal ancestry by connecting you with other individuals who are descendants of a shared common matrilineal ancestor.<\/p>\n<p>With a simple cheek swab, our premier suite of DNA tests provides clues to help further traditional genealogical research, determine ethnic and geographic origins and discover shared ancestry across all lines. To that end, genetic genealogy offers those interested in their family history the opportunity to break through brick walls, connect with living relatives across the globe, and confirm or refute suspected connections between families.<\/p>\n<p>Happy testing![\/vc_column_text][\/vc_column][\/vc_row]<\/p>\n<\/section>","protected":false},"excerpt":{"rendered":"<p>Genetic genealogy is the use of DNA testing to determine relationships between individuals, find genetic matches and discover one\u2019s ancestry.<\/p>\n","protected":false},"author":8,"featured_media":74408,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"om_disable_all_campaigns":false,"footnotes":""},"categories":[1209,1210,1211],"tags":[1176,1190,1193],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v21.2 (Yoast SEO v21.7) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>What is Genetic Genealogy Anyway?
