Millions of Americans are fascinated with their heritage---- digging into their family tree to find out about their ancestors. The newest trend in finding out where we came from is genetics, a scientific process being brought to the masses by websites like Ancestry.com and 23andme.com.
DNA genetic testing can show what part of the world your ancestors came from, identify possible health issues that run in your family, and even help you find long-lost relatives.
Genetics also determine things like your eye color, if your hair is curly or straight, or whether you have a widow's peak or dimples.
