DNA testing has been around for a long time now. Many of us make use of simple at-home kits to learn more about ourselves and our ancestry. This was the initial plan with DNA kits on a commercial level. Users could find out the lineage, with many tracking that goal of Viking blood. Others use it for health reasons, such as looking for genes that determine health issues, weight gain links, and other biologically determined factors.
The easier it becomes to sequence a genome and understand the component, the more we can learn about ourselves. One area that is interesting to both singles and couples is the idea of DNA matchmaking.
