[The aspects of a molecular-genetic study of human hair depending on their morphological characteristics. II. The peculiarities of genotyping].

The objective of the present study was to optimize genotyping of nuclear DNA contained in human hair. The most efficient procedures for DNA isolation and typing are described taking into consideration the hair growth phase, the epithelial tissue conditions, and the number of nuclei in the near-root ends of the hair. The recommendations for the expert interpretation of the results of the molecular-genetic investigations are proposed.
