COMPARISON OF QUANTITATIVE GENETIC PARAMETERS [PDF]
Evolution, 1992 Shaw (1991) has described a maximum-likelihood procedure for comparing genetic covariance matrices between populations. While her efforts to expand the procedures available for quantitative genetic analyses are laudable, her discussion is incomplete in several respects. For example, consider her criticism of Dietz's matrix permutation test (Dietz, 1983)

Estimation of quantitative genetic parameters [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2005 This paper gives a short review of the development of genetic parameter estimation over the last 40 years. This shows the development of more statistically and computationally efficient methods that allow the fitting of more biologically appropriate models. Methods have evolved from direct methods based on covariances between relatives to methods based

Genetic parameters of sole lesion recovery in Holstein cows
Journal of Dairy Science, 2023 : Sole hemorrhage and sole ulcers, referred to as sole lesions, are important causes of lameness in dairy cattle. The objective of this study was to estimate the genetic parameters of a novel trait reflecting how well cows recovered from sole lesions and
