Mapping DNA can have a couple of different meanings, one is the ability to trace out DNA and “Map” the heritage contained in the DNA. The other is making a map of the DNA. Ancestry.com now does both.
You can put your DNA info and those of family in your family tree.
For those who might not know their heritage, DNA search could really help. Of course privacy is a concern and measures are taken to protect the information, but you have to admit that science is giving us some pretty neat things in DNA Discovery.
