Relationship between Observed Components of Variance and Causal Components of Variance in a Split-Family, Half-Sib, Full-Sib Analysis

In the first of two papers presenting a quantitative-genetic analysis of larval performance by the fly, Liriomyza sativae , on two different host plants, Via (1984) used a split-family, half-sib, full-sib design to calculate causal components of variance using "the usual theoretical relationshi...

Description
Summary:In the first of two papers presenting a quantitative-genetic analysis of larval performance by the fly, Liriomyza sativae , on two different host plants, Via (1984) used a split-family, half-sib, full-sib design to calculate causal components of variance using "the usual theoretical relationships between genetic variance and the observed variance among half- and full-sib families". However, the equations are incorrect and, therefore, the calculated variance component estimates are incorrect. The purpose of this note is to provide the correct relationships between causal components of variance and observed variances in a split-family, half-sib, full-sib design.
