Allison Plowden said, "The laws of genetics apply even if you refuse to learn them." Clearly the late English historian and biographer, known for her popular non-fiction about women of the Tudor period, recognized that genetic terminology is a foreign language to many of us. Genetics refers to the study of genes and their roles in inheritance. Given genetics is the basis of all living organisms, and DNA genealogy testing is a great resource for family researchers who have tapped out the paper trail on a project, I have put together a primer to help you understand genetic terms a little better. Think of DNA (deoxyribonucleic acid) as a human blueprint, because it holds the code for all genetic information. As early as 1952, the Hershey-Chase experiment showed that DNA is the molecule responsible for inheritance. The twisted ladder we have come to equate with DNA was discovered 1953 when James D. Watson and Francis Crick determined the structure of DNA, using X-ray crystallogr...

Modern medical science has produced a massive number of incredible discoveries over the last couple of decades, but all of them are outshined by the fact anyone with a little spare cash can now have their genetic profile mapped out in as little as 6-8 weeks by doing nothing more than producing a small vial full of their own saliva. After spending decades as nothing more than a science fiction dream and years as a procedure only available for the wealthiest of individuals, genetic mapping has gone mainstream, and you and I are poised to reap the benefits. One of the most popular and well-known personal genome mapping services on the market today is the 23andme genetic testing service. Take a minute to read up on 23andme and to discover why it represents such an incredible advance in medical science. The Procedure It's easy to hear the words "personal genetic mapping" and assume it's a complicated procedure that can only be performed by the most technically minded of i...
