[Table method of the component expansion of phenotypic variance based on correlations between relatives]

Tables are proposed which allow to ease and unify calculations of component partitioning of the phenotype variance based on the "least squares methods". Combinations of additive and dominant genetic components and four common environmental ones are considered. To use tables, information is needed about correlations among following types of relatives: 1) MZ and DZ twins, parent-offspring; 2) siblings, parent-offspring, second degree relatives; 3) the first variant and sibling; 4) the third variant and second degree relatives.
