Calculation of heritability for aquaculture nest design and its implementation on SPSS
Nested design is one of the important genetic designs in aquatic breeding,and the calculation of its heri-tability involves the selection of squares and types,the selection of fixed or stochastic models,and model modifica-tion,etc.If the processing factors are included in the wrong order,the nested design analysis of variance cannot be completed through the operation of the SPSS graphic dialog box.Taking the textbook data as an example,the paper introduces the basic principles of nested design ANOVA,uses the dialog box pasting procedure in SPSS software for programming,and demonstrates the estimation of variance components and the calculation of heritability through the process of general linear modeling,and discusses and explains the necessity of model selection,sum-of-squares type selection,and the programming of nested design ANOVA in SPSS,etc.,which can provide practical refer-ences for teaching and scientific research.It can provide practical reference for teaching and research.
