Özet

The aim of this study was to determine the effects of rank transformation on estimations of genetic parameters for non-normally distributed four simulated variables. X-1, X-2, X-3, X-4 have means and variances of 10, and the variables originated from Laplace distribution, Poisson distribution, Uniform distribution, Weibull distribution, respectively. After rank transformation, these values are 0 and 1 for each variable, respectively. Except the Poisson distribution all variables has been transformed into Gaussian distribution by rank transformation. It was determined that genetic information loss did not occur in any of the variables with normally distributed by rank transformation. It is possible to say that rank transformation can be used safely in quantitative genetic analyzes with regard to research results.
