What are the odds of inheriting no DNA from a great, great, great grandparent?| DNA is passed down to the next generation in big chunks called chromosomes. Every generation, each parent passes half their chromosomes to their child. What most people forget, though, is that our chromosomes get mixed and matched before they are passed on. It is because of this "recombination" that your great, great, great grandparent's DNA is almost certainly still lurking in yours. #DNA #familyhistory
