This gives you access to the video of Kathy Johnston’s one-hour presentation on August 16, 2014 entitled “From X Segments to Success Stories: The Use of the X Chromosome in Genetic Genealogy”. The X chromosome has a unique pattern of inheritance. A male gets his X chromosome from his mother only. A female gets two X chromosomes, one from each parent. Kathy spoke on the basic science and practical uses for the X chromosome in genealogy. Learn what is new, how the X chromosome can be used to find a biological parent and explore what is available to the citizen scientist.

Dr. Kathy Johnston, a retired dermatologist, has been engaged in genealogical research for over 25 years. She has been active in genetic genealogy since 2004, at which time she started collecting DNA samples from her aging parents in order to identify their Y-DNA and mitochondrial DNA lines. She has had a special interest in the X chromosome since 2008 because of its unique pattern of inheritance and the richness of its ancestry informative markers. Kathy has been active in the DNA Interest Group of the Southern California Genealogical Society (SCGS) and the International Society of Genetic Genealogy (ISOGG). As a volunteer, she helps genealogists understand their direct-to-consumer DNA test results. She is a volunteer administrator for several projects at Family Tree DNA. She was a volunteer at the very first “Family History and DNA: Genetic Genealogy in 2013″ conference co-sponsored by SCGS and ISOGG and will be speaking at the same conference this year in Burbank, California on June 5, 2014. In September 2013, she along with other members of ISOGG, was invited to attend an historic ancestry inference roundtable discussion organized by the American Society of Human Genetics (ASHG). In October, 2013 in Boston, she presented a scientific poster during the Ethical, Legal, Social and Policy Issues in Genetics Session at the ASHG 63rd Annual Meeting.
