Genetic heterogeneity of residual variance for growth traits in American angus Cattle.

Journal of animal science - 8 Jan 2026

Abstract excerpt

Economic incentives have increased the demand for uniformity in beef production, making it a valuable phenotype for genetic studies. Genetic heterogeneity of residual variance suggests that variability around the mean may have a genetic component and could potentially respond to selection. However, evidence for genetic control of residual variance in beef cattle remains limited. The objectives of this study were...
