Mitochondrial DNA Analysis at the FBI Laboratory
Microscopic Comparison of Hairs
A primary visual analysis is performed on hairs before they are analyzed in the FBI Laboratory using a comparison microscope. Microscopic characteristics of hairs from known sources are compared to hairs from questioned sources to determine if they can be associated with each other.
