On a method of estimating the genetic correlation between characters measured in different experimental units.

R L Fernando1, S A Knights, D Gianola.   

Abstract

Yamada's method of estimating genetic co-variances between traits measured in different experimental units is discussed. It is shown that if the data are unbalanced, this method gives biased estimates of genetic covariances unless the traits have identical genetic and residual variances. An alternative unbiased procedure is suggested.
