The Mormon Times web site has a new 16-minute video that explains DNA and its connection to genealogy. Scott R. Woodward, executive director of Sorenson Molecular Genealogy Foundation, explains what DNA is, what it can teach us, what its weaknesses are and how it can be used to understand and track relationships between individuals and groups.
Woodward discusses the difference between the portions of DNA that are used to track groups and used to identify specific individuals. He explains the difference between using mitochondrial DNA, which tracks only the female line, and Y-Chromosome DNA, which tracks the male line.
