Genetic parameter estimation has advanced significantly over 40 years, driven by animal breeding and selection. The animal model with residual maximum likelihood (REML) revolutionized quantitative genetic analysis for both artificial and natural populations.

Area of Science:

  • Quantitative genetics
  • Animal breeding
  • Evolutionary biology

Background:

  • Genetic parameter estimation is crucial for animal selection experiments and breeding programs.
  • Traditional methods have limitations in analyzing complex genetic processes.

Purpose of the Study:

  • To review the development of genetic parameter estimation methods over the past 40 years.
  • To highlight the impact of the animal model and residual maximum likelihood (REML) on quantitative genetic analysis.
  • To explore the application of these methods in both artificial selection and natural populations.

Main Methods:

  • Review of historical developments in genetic parameter estimation.
  • Focus on the animal model and residual maximum likelihood (REML) techniques for mixed models.
