Covariance Analysis
Covariance analysis is the analysis of how traits vary - either the tendency of 2 different traits to be inherited together, or the degree to which a single trait tends to be similar amongst relatives.
Two forms of covariance analysis are included.
Familial covariance analysis is where the heritability of a given trait - typically a polygene - is estimated by examining the 'values' of that trait between related individuals. The following relationships can be analysed: parent-offspring, full siblings, half-siblings, sire-side siblings and dam-side siblings. 'Heritability' means the degree to which a given trait is determined through inheritance. Depending on the relation analysed this form of covariance analysis can estimate either 'broad sense heritability' (H2) or 'narrow sense heritability' (h2).
Covariance analysis between traits measures the degree to which any 2 traits - typically polygenes - are inherited alongside each other.
