The first cousin-matching autosomal DNA tests became available in 2009. Sales have exploded in the last few years and over 30 million people have now tested. However, the currently available tests still have many limitations. It is important to consider these uncertainties when incorporating DNA evidence into genealogical research. As the cost of sequencing comes down, the current microarray tests will be replaced by whole genome sequencing. In this talk we look at some of the pitfalls of interpreting matches based on incomplete data and look ahead at some of the exciting developments we can expect to see in the coming years.
