About the data designs for estimation of genetic parameters in animal breeding studies
The simple random one-way linear model and ANOVA estimators of random effects, variance components and intraclass correlation are studied. A related sire model in animal genetic studies is considered. The study is focused on the effect of data design on the accuracy of estimates. The patterns of sampling variances of estimates depending on the genetic determination of the trait and data design are examined and optimal designs for different genetic parameters are compared in the balanced case.
