Abstract: MOST animal breeding systems are based on the selection of genetically superior parents. Where the phenotype is not a reliable expression of the genotypic constitution, as in the case of a quantitative character such as egg production, which is controlled by multigenic inheritance, selection must be based on estimating the genetic value of an animal by examining records from groups of close relatives. It is then necessary that the characters under observation be defined quantitatively and average values of the groups compared. Moreover, preliminary work is often required to determine which of a number of characters should be isolated and assessed or measured. It is necessary also to determine the most reliable and efficient method of assessment for any given level of accuracy and to define the number of animals necessary to ensure that differences between groups are statistically significant. Although such problems have been investigated and discussed previously …
