Effectiveness of adjusting for heterogeneity of variance in genetic evaluation of Japanese Black cattle.

Journal of animal science - 1 Oct 2007

Abstract excerpt

Heterogeneity of variance among subclasses of an effect is a potential source of bias in genetic evaluation. The objectives of this study were to quantify the heterogeneity of variance in carcass weight in Japanese Black cattle, to develop an adjustment method to account for the heterogeneity, and to evaluate the effectiveness of the method. A total of 96,950 records were collected from steers and heifers...
