Estimation of quantitative genetic parameters [PDF]

open access: yesProceedings of the Royal Society B: Biological Sciences, 2008
This paper gives a short review of the development of genetic parameter estimation over the last 40 years. The need to analyse genetic processes in both animal selection experiments and animal breeding improvement programmes motivated the majority of this work.
