For ordering information and detailed descriptions on Advanced Genetic Genealogy: Techniques and Case Studies please see this page which includes links to book sellers, reviews, and a book descrpition. This is the first genetic genealogy book focusing on advanced analysis techniques using case studies to demontrate the principles. This book assumes the reader is already familiar with the basic concepts covered in Genetic Genealogy in Practice.


For ordering information and detailed descriptions on Genetic Genealogy in Practice please see this page which includes links to a topic list, reviews, and awards. This is the first genetic genealogy workbook. This book covers the biological basics, types of DNA testing that are useful for genealogy, and analysis techniques needed for successful genetic genealogy. No matter which company a person tested at or which tools are used for data collection and analysis, the information in this book will help a researcher correlate DNA evidence into a family study.
