The Power of X to unlock Family Mysteries (Martin Hayden)

GGI2020 Belfast - DNA testing has in recent years given lots of focus to autosomal and yDNA testing whilst often neglecting the “Power of the X Chromosome”. This talk will explain the X chromosome, its inheritance patterns, how it differs from the Y chromosome and mitochondrial DNA. The talk will conclude with a worked example of how it can be used to confirm a family line. This lecture was presented at Genetic Genealogy Ireland 2020 in Belfast.
