During the investigation, several types of evidences i.e. physical, chemical or biological are recovered in numerous conditions from the scene of occurrence. These evidences play a vital role in the identification of an individual involved in a crime. Over the years, DNA has been used a source for determination of species and establishing the personal identification from various sources i.e. hairs, nails, sweat etc. Hairs are the physical evidences frequently encountered in various conditions. The Two of the features that make hair a good subject for establishing individual identity are its resistance to chemical decomposition and its ability to retain structural features over an extended period. Hairs, which are composed primarily of the protein keratin, can be defined as slender outgrowths of the skin of mammals. This study was focused on the determination of individuality and establishment of inheritance from the keratin phenotypes pattern found in the hairs samples of hairs in the North Indian population. The results of this study present the slight variation among both genders and conclude that gender discrimination is not possible from keratin phenotypes. While the occurrence of keratin K1, K2, K3, have higher percentage of inherited pattern from parents.
