INHERITANCE OF SELECTION TRAITS

   The article presents an analysis of genetic and selection indicators of breeding anim als of the Kazakh white-headed breed. Due to the fact that inherited traits have their own characteristics and differences, we use the heritability coefficient. The value of this indicator is the selection of traits in a group of animals based on hereditary characteristics. A lower heritability value, in contrast, has a smaller impact on group selection of animals. To improve the herd, animals m ust be selected based on the variability of traits. When conducting mass selection of young animals at an early age, the repeatability of live weight is observed until the complete formation of body weight.
