Genetic and phenotypic parameters for body and yearling fleece weigh traits were estimated based on 4008 records. Records gathered across year 1993 to 2007 in the Markhoz goat research stations in Saghez and Sanandaj. Parameters were estimated using univariate and bivariate animal model with restricted maximum like lihood ASREML software. Mean (standard error of means) of birth weight (BW), w...
Genetic robustness, the invariance of the phenotype in the face of genetic perturbations, can endow the organism with reduced susceptibility to mutations. A large body of work in recent years has focused on the origins, mechanisms, and consequences of robustness in a wide range of biological systems. Despite the apparent prevalence of mutational robustness in nature, however, its evolutionary o...
In this study, selection strategies were simulated to find optimal selection strategy in Japanese quails. Breeding goal was consisted of body weight and egg weight traits. Effects of using genetic markers related to carcass weight were investigated by five different selection strategies. In this case, breeding goal included body weight, egg weight and carcass weight. Deterministic simulation, b...
