Abstract: Phenotypic expression of a trait is a function of both the genotype of the animal and the environment that influences it. Connectedness among management units is of concern in genetic evaluation. In this study, for considering effect of genetic connectedness effect on the genetic evaluation, comparisons of estimated evaluations and genetic parameters in two cases lack and un-lack (GC) have been written in the C++ language program by simulation method in sheep herds with consideration of natural conditions (fertility percent, mortality percent). It is argued that connectedness increases as the proportion of offspring from common sires. A high level of connections improved the accuracy of the genetic evaluation. Connectedness ratings were higher for highly heritable traits and lower for traits with low heritability.
