“Genetics explains why you look like your father, and if you don’t, why you should.”– Anonymous
You might have heard about genetic projects, such as mapping the human genome or tracing the origins of Kennewick Man, Cheddar Man, Ice Man or Ice Maiden. In addition to these famous projects, genealogists are beginning to use genetic testing to solve some of the mysteries not answered by paper records. One type of analysis uses the y chromosome (yDNA), which passes only through the male line. Another type of analysis uses mitochondrial DNA (mtDNA), which passes only through the female line. Geneticists can’t yet resolve other lines (for example, a mother’s father’s line or father’s mother’s line), but those lines can often be traced using genetic tests on a relative for whom the line is strictly paternal or strictly maternal.
Paternal DNA (yDNA)
All modern humans descend in the male line from a particular man, nicknamed “Genetic Adam,” who lived about 60,000 years ago. All living men have inherited his y chromosome (yDNA), along with the mutations that have accumulated in our individual family lines.
- Information about yDNA is now hosted at HauriDNA.com.
Maternal DNA (mtDNA)
All modern humans descend in the female line from a particular woman, nicknamed “Mitochondrial Eve,” who lived about 150,000 years ago. Each of us has inherited her mitochondrial DNA (mtDNA), along with the mutations that have accumulated in our individual family lines.
