A placeholder to explain how the CE, microarray testing and sequencing work — from a perspective of the data they collect and roughly how much and how parallel. Like the DNA Primer page, to give some more detail and context to how the test process and results are effective and limited. To help people understand them as tools — how they can be used and what their limitations on use are. Maybe to explain the 3rd wave of genetic genealogy we are now entering with widespread use of WGS testing possible and the promise of its next generation on the horizon. And what limitations it still has!
