Ann, I really appreciated this article. I watch this list as an eager novice, knowing I have a steep learning curve, and having gained much knowledge from the talented people who contribute here. Hopefully this is appropriate to ask here, again given my novice status. What I have trouble wrapping my head around in this article, particularly given the DNA doesn't lie, DNA is a fact and end all, be all, is how does Germline allow matches to jump back and forth between segments? Isn't this counter intuitive to something directed at extracting genetic code? And without asking too much of the scientific end, how is that even possible. How can DNA move to other sections? Perhaps DNA isn't as black and white as I have been led to view it. I don't see it as fluid. But while coding appears to not fluctuate, I guess I am seeing that perhaps the testing makes it so. Thank you!
