“…Genetic evaluation using an animal model in considering the effects of X chromosome inheritance has been proposed [56,73]. Several studies have used this model to estimate the X-linked additive genetic effects using real data (e.g., [74][75][76]), while Meyer [77], with computer simulation, showed the difficulty in accurate estimation of X-linked effects. Wittenburg et al [78] used the statistical model in considering autosomal and gonosomal (X and Y chromosomes) effects to estimate genetic parameters of piglet birth weight.…”

The genetic contribution with respect to autosomal genes has been widely used to evaluate the genetic diversity of a target population. Here, we developed a method to calculate the genetic contribution with respect to genes on sex chromosomes and mitochondrial DNA through pedigree analysis. To demonstrate the performance, we applied the methods for calculating genetic contributions to example pedigree data. To verify the results of genetic contribution calculations, we performed gene-dropping simulations mimicking flows of genes on autosomes, X and Y chromosomes, and mitochondrial DNA, and then compared the results from the simulation with the corresponding genetic contributions. To investigate the effect of pedigree error, we compared the results of genetic contribution calculations using pedigree data with and without errors. The results of gene-dropping simulation showed good agreement with the results of the genetic contribution calculation. The effect of pedigree errors on the calculation of genetic contribution depended on the error rate. Since the patterns of the genetic contributions of such genes might be different from those on autosomes, the novel approach could provide new information on the genetic composition of populations. The results are expected to contribute to the development of methods for sustainable breeding and population management.

The aim of this study was to compare non-linear models to determine which model describes the growth pattern best for daily weight records of Mehraban sheep. The Nonlinear Negative exponential, Brody, Gompertz, Logistic, and von Bertalanffy models were applied. The data was collected between 2001 and 2010 from Mehraban breeding unit of the Agriculture Organization of Hamadan province in western Iran that were included 8299 daily weight records from 2206 animals from birth to 409 days of age. The NLIN procedure in SAS software was used to evaluate changes in body weight among different weighing age. The best model was determined by Adjusted Coefficient of Determination (), Root Mean Square Error (RMSE) criteria, Akaike's information criteria (AIC) and Bayesian information criteria (BIC). For all models, were mostly higher than 93%. Based on used criteria, the Brody model was selected as the best Model to explain the biological growth of Mehraban sheep. The results revealed that the Brody model can be practically useful for setting management strategies such as determining nutritional programs and the appropriate age for slaughter of Mehraban sheep.
