Book Description
How many DNA testing companies will show you how to interpret DNA test results for family history or direct you to instructional materials after you have had your DNA tested? Choose a company based on previous customer satisfaction, and whether the company gives you choices of how many markers you want, various ethnic and geographic databases, and surname projects based on DNA-driven genealogy. Before you select a company to test your DNA, find out how many genetic markers will be tested. For the maternal line, 400 base pairs of sequences are the minimum. For the paternal line (men only) 37 markers are great, but 25 markers also should be useful. Some companies offer a 12-marker test for surname genealogy groups at a special price. Find out how long the turnaround time is for waiting to receive your results. What is the reputation of the company? Do they have a contract with a university lab or a private lab? Who does the testing and who is the chief geneticist at their laboratory? What research articles, if any, has that scientist written or what research studies on DNA have been performed by the person in charge of the DNA testing at the laboratory? Who owns the DNA business that contracts with the lab? How involved in genealogy-related DNA projects and databases or services is the owner?

Book Description
“A fascinating exploration of the mysteries ignited by DNA genealogy testing—from the intensely personal and concrete to the existential and unsolvable.” —Tana French, New York Times–bestselling author You swab your cheek or spit in a vial, then send it away to a lab somewhere. Weeks later you get a report that might tell you where your ancestors came from or if you carry certain genetic risks. Or, the report could reveal a long-buried family secret that upends your entire sense of identity. Soon a lark becomes an obsession, a relentless drive to find answers to questions at the core of your being, like “Who am I?” and “Where did I come from?” Welcome to the age of home genetic testing. In The Lost Family, journalist Libby Copeland investigates what happens when we embark on a vast social experiment with little understanding of the ramifications. She explores the culture of genealogy buffs, the science of DNA, and the business of companies like Ancestry and 23andMe, all while tracing the story of one woman, her unusual results, and a relentless methodical drive for answers that becomes a thoroughly modern genetic detective story. Gripping and masterfully told, The Lost Family is a spectacular book on a big, timely subject. “An urgently necessary, powerful book that addresses one of the most complex social and bioethical issues of our time.” —Dani Shapiro, New York Times–bestselling author “Before you spit in that vial, read this book.” —The New York Times Book Review “Impeccably researched . . . up-to-the-minute science meets the philosophy of identity in a poignant, engaging debut.” —Kirkus Reviews (starred review)

Pages : 250
Book Description
You don't have to learn everything about genetic genealogy before asking specific questions of your DNA! That's the premise of Diahan Southard's brand new book, Your DNA Guide - the Book, now available for pre-order at a special sale price. Your DNA Guide - the Book is like no other genetic genealogy book on the market. Instead of learning more-than-you-need-to-know in textbook style, you'll choose a specific DNA question to start exploring right away. You'll follow concrete step-by-step plans, learning important DNA concepts--in plain English--as you go. Do you want to learn who your 2X great grandmother is? Turn to page 23. Do you want to know how you are related to one of your DNA matches? Page 37. As you proceed, you check your progress and get new guidance based on your specific results at each stage. (Including troubleshooting, like when your matches just aren't responding or your great-grandparents turn out to be first cousins.) This powerful, hands-on approach is based on Diahan's 20 years of experience in the genetic genealogy industry and especially in the past five years, as she helps clients one-on-one make DNA discoveries. It became clear to her that while each client's situation may be unique, there are patterns in how you can find solutions that you can apply yourself. Your DNA Guide - the Book is for anyone who has taken a DNA test or may want to. It helps genealogists reconstruct family trees. It helps adoptees identify biological relatives. It can help you identify a specific DNA match. In short, it helps anyone explore what their DNA--and their DNA matches--can tell them about their origins.

Understand Your Dna: A Guide

Languages : en
Pages : 105
Book Description
Are you considering to test your own DNA? Do you want to learn more about your health and ancestry? Understand your DNA — A Guide is about what you can use genetics for. For a few hundred dollars, you can now scan your own genes. Millions of people all over the world have already done so. Everyone wants to see what they can get to know about themselves, and the market growing rapidly. But what does it require from you? And what can you really use a DNA test for? Understand your DNA — A Guide helps you put the plots and charts of consumer genetics into perspective and enables you to figure out what's up and down in the media headlines. The book is also a key input for today's debate about what we as a society can and want to do with medical genetics. Genetics will play a growing role in the future. Understand your DNA — A Guide is an easy-to-read and necessary guide to that future. The book is provided with a foreword by Professor Sham Pak-Chung of Hong Kong University.While there are many books about genetics, they typically take the perspective of a scientist wanting to understand the molecular levels. At the same time, direct-to-consumer genetics is a booming market, with millions of people already tested. Very little has been published that will guide them for real, because the need here is more focused on medical and practical understanding, than focussed on molecules.This book therefore aims to hit that vacant spot in the market. It's a walk-through of all concepts that are necessary to understand in your own analysis. Meanwhile, it is also limited in scope to only those concepts — thus distinguishing it from broader works.The book is appropriate for the readerships in modern multi-ethnic metropolises because it mixes European and Asian examples, both from the collaboration between the author from Europe and the foreword-writer, Prof. Pak Sham of Hong Kong University. But also, because many of the examples in the book concerns differences and similarities between Asian and European ethnicities, something the author believes is a trend in time.Related Link(s)

Finding Family: My Search for Roots and the Secrets in My DNA is the highly suspenseful account of an adoptee trying to reclaim the biological family denied him by sealed birth records. This fascinating quest, including the author's landmark use of DNA testing, takes readers on an exhilarating roller-coaster ride and concludes with a twist that rivals anything Hollywood has to offer. In the vein of a classic mystery, Hill gathers the seemingly scant evidence surrounding the circumstances of his birth. As his resolve shores up, the author also avails of new friends, genealogists, the Internet, and the latest DNA tests in the new field of genetic genealogy. As he closes in on the truth of his ancestry, he is able to construct a living, breathing portrait of the young woman who was faced with the decision to forsake her rights to her child, and ultimately the man whose identity had remained hidden for decades. Finding Family offers guidance, insight, and motivation for anyone engaged in a similar mission, from ways to obtain information to the many networks that can facilitate adoption searches. The book includes a detailed guide to DNA and genetic genealogy and how they can produce irrefutable results in determining genetic connections and help adoptees bypass sealed records and similar stumbling blocks.

Native American DNA
Author: Kim TallBear
Publisher: U of Minnesota Press
ISBN: 0816685797
Category : Social Science
Languages : en
Pages : 241
Book Description
Who is a Native American? And who gets to decide? From genealogists searching online for their ancestors to fortune hunters hoping for a slice of casino profits from wealthy tribes, the answers to these seemingly straightforward questions have profound ramifications. The rise of DNA testing has further complicated the issues and raised the stakes. In Native American DNA, Kim TallBear shows how DNA testing is a powerful—and problematic—scientific process that is useful in determining close biological relatives. But tribal membership is a legal category that has developed in dependence on certain social understandings and historical contexts, a set of concepts that entangles genetic information in a web of family relations, reservation histories, tribal rules, and government regulations. At a larger level, TallBear asserts, the “markers” that are identified and applied to specific groups such as Native American tribes bear the imprints of the cultural, racial, ethnic, national, and even tribal misinterpretations of the humans who study them. TallBear notes that ideas about racial science, which informed white definitions of tribes in the nineteenth century, are unfortunately being revived in twenty-first-century laboratories. Because today’s science seems so compelling, increasing numbers of Native Americans have begun to believe their own metaphors: “in our blood” is giving way to “in our DNA.” This rhetorical drift, she argues, has significant consequences, and ultimately she shows how Native American claims to land, resources, and sovereignty that have taken generations to ratify may be seriously—and permanently—undermined.

Book Description
Here's how to open your own online DNA-driven genealogy reporting/interpreting service business. You wouldn't do the actual DNA testing. The laboratory you contract with does the testing and sends you reports that you interpret for your clients. As a DNA-driven genealogist, you would prepare illustrated and text-driven reports, colorful CDs, brochures, press kits, covers, Web sites, and guides to interpreting the DNA-for-ancestry-based information. You would interpret tests for deep ancestry to your clients. What verbal skills and any other preparation would you need to empower consumers with knowledge from reports you receive from your partnering DNA-testing laboratory? Would you also interpret reports from genetics counselors testing for predisposition to diseases? Or emphasize only deep ancestry? Would you need a self-taught science background, a genealogy hobby, or only marketing and communications experience? Who does the actual interpreting? How would you contract with DNA laboratories to send reports and other information related to ancestry? You may be a genealogist, a personal historian, or a life story videographer thinking of partnering with a DNA-testing laboratory. Your business would be to make complex information easy to understand and interpret in plain language DNA reports from scientists to genealogy clients and surname groups. The DNA tests could be for ancestry and/or nutritional genomics issues.

The Beginner's Guide to Interpreting Ethnic DNA Origins for Family History
Author: Anne Hart
Publisher: iUniverse
ISBN: 0595283063
Category : DNA.
Languages : en
Pages : 262
Book Description
Genealogists are now using molecular genealogy--comparing and matching people by matrilineal DNA lineages--mtDNA or patrilineal Y-chromosome ancestry and/or racial percentages tests. People interested in ancestry now look at genetic markers to trace the migrations of the human species. Here's how to trace your genealogy by DNA from your grandparents back 10,000 or more years. Anyone can be interested in DNA for ancestry research, but of interest to Jews from Eastern Europe is to see how different populations from a mosaic of communities reached their current locations. From who are you descended? What markers will shed light on your deepest ancestry? You can study DNA for medical reasons or to discover the geographic travels and dwelling places of some of your ancestors. How do Europeans in general fit into the great migrations of prehistory that took all to where they are today based on their genetic DNA markers and sequences? Where is the geographic center of their origin and the roots of all people? Specifically, how can you interpret your DNA test for family history as a beginner in researching ancestry and your own family history?
