Even if you have already traced your family tree back six generations, there's always more you can learn from your DNA. Give someone you love a 23andMe Health + Ancestry Service kit ($149, originally $199) so they can discover what their genes have to say about their health, traits, and ancestry. They can learn how their DNA breaks down across more than 150 regions worldwide, find out how much Neanderthal DNA they inherited, and even opt in to connect with others who share DNA with them.
