The article studies 22 traits in various genes and identification of the novel relations for the hair morphology. The studies have revealed that most of the human, physical characteristics such as hair morphology can indeed be inherited from the parent organisms. A survey had been carried out for many people, and together with the company’s examinations, participants revealed associations in certain Single Nucleotide Polymorphisms (SNPs). Sheka, Sri N. et al. (2008). Linkage and Association Analysis of Spectrophotometrically Quantified Hair Color in Australian Adolescents: the Effect of OCA2 and HERC. Journal of Investigative Dermatology. 128, 2807–2814. The article provides the results of investigation by the Genetic Epidemiology unit in Brisbane, Queensland, Australia. It shows how the genetic studies of pigmentation have benefited from the spectrophotometric measures of light to dark hair color. The article insists on having accurate reference measurements when carrying out any studies concerning the variations due to the genetic influences. According to the studies, the investigations concerning the hair color have turned to the spectrophotometric measurements, as well as the biochemical quantification. In using spectrophotometric methods, a wavelength of 650nm is used as it has the greatest power to differentiate the different amounts of dermal melanin. The associations were analyzed that the OCA2 and HERC2 to determine the allele difference in various populations. However, the spectrophotometric method cannot be said to be a confirmation therefore, further methods should be carried out to determine the complement of genes infl uencing hair color. The study also should determine if the spectrophotometry has any importance over prepared ratings. The study also quantifies the amount of pigments for the light and dark
