Abstract

The number of observations required to obtain reliable estimates of heritability has been discussed recently for the method which utilizes the intra-class correlation coefficient. Wearden (1959) has made use of the power function to determine the number of progeny per sire needed to estimate heritability. Tallis (1959), utilizing the formula for the variance of the intra-class correlation coefficient as given by Fisher (1952), has discussed the minimum number of offspring necessary for estimating heritability with a given accuracy.
