The relation between phenotypic variability and heterozygosity for a polyallelic polygenic trait is obtained using computer simulation. It is shown that unlike the di-allelic case, the variance of phenotypic score of the trait can increase or decrease depending on the allele frequency distribution. The relevance of this to selection is discussed.
