Estimation of the fathers genotype on productivity their descendants

Stochastic variability of tribal value of the bulls have defined with the help of a bootstrap procedure. The authors determined the intervals of tribal value of bulls on bootstrap's samplings, BLUP-estimations and program 2. It was shown that the intervals of tribal value of bulls established on bootstrap's samplings, negatively correlated with quantity of the daughters of bulls and herds, in which ones were used. The authors discuss the expediency of bootstrap's procedure for statistic selectional-genetic programs on genotype estimation of agricultural animals and birds.
