When using DNA test results as evidence in genealogy, it's important to understand contextual information about DNA inheritance patterns and amounts of DNA shared between relatives. This contextual information can turn raw DNA data into genealogical evidence. In this post I will share several charts that give meaning to the data in our DNA test results. The charts I'm sharing are freely available online. Another excellent source for inheritance charts is the book Genetic Genealogy in Practice by Blaine T. Bettinger and Debbie Parker Wayne. The charts in the book are well done and helpful for understanding the inheritance of autosomal...
A great way to get the most out of the list of your DNA matches is to separate the people into groups that cluster around one of your ancestral lines. If you can divide your match list into groups, you can focus on finding the most recent common ancestor (MRCA) that you share with that cluster of people. Once that common ancestor or ancestral couple is identified, you can focus your research on one familial line, and identify the DNA that you inherited from the common ancestor(s). The groups of related people are sometimes called “Clusters” or “Genetic Networks.” Goals...
