Abstract
The purpose of this project is to investigate the pigmentation of skin by the use of genetic markers. In order to do this a multivariate linear model is used, since there are repeated observations for each person on 3 different positions of the body. Of these multivariate linear models, the GMANOVA is chosen. This project will only focus on predicting pigmentation. First the theory regarding GMANOVA is introduced and then the GMANOVA is implemented into R, and hereafter it is used to analyse the pigmentation using only the genetic markers. Then the results are discussed in the last chapter. This project found four genetic markers as the most important for predicting pigmentation; rs12913832, rs1408799, rs1800407, rs2470102 for a p-value of 0.05.
