Introduction
A human genome contains over 3 billion base pairs. Now, if a scientist wants to identify similar portions of DNA in a human genome to a chimpanzee genome, which is also over 3 billion base pairs long, the scientist would need to use a computer program. This is where CoGe comes in. CoGe can be used to quickly take a section of a 3 billion base pair genome and find where that section closely matches another genome. As you finish this lesson you will not only begin to understand how genetics may be used to determine ancestry but also understand how scientists can estimate the when separate species shared a common ancestor.
