and a pioneer in
animal breeding
Animal breeding is a branch of animal science that addresses the evaluation (using best linear unbiased prediction and other methods) of the genetic value (estimated breeding value, EBV) of livestock. Selecting for breeding animals with superior ...
— the application of quantitative methods for the genetic evaluation of domestic livestock. This is critically important because it allows farmers and geneticists to predict whether a crop or animal will have a desired trait, and to what extent the trait will be expressed. He developed
mixed model
A mixed model, mixed-effects model or mixed error-component model is a statistical model containing both fixed effects and random effects. These models are useful in a wide variety of disciplines in the physical, biological and social sciences.

equations to obtain
best linear unbiased predictions of breeding values and, in general, any random effect. He invented three methods for the estimation of
variance components in unbalanced settings of mixed models, and invented a method for constructing the inverse of
Wright's numerator
relationship matrix based on a simple list of pedigree information. He, with his Ph.D. student
Shayle R. Searle, greatly extended the use of matrix notation in statistics. His methods are widely used by the domestic livestock industry throughout the world and are a cornerstone of linear model theory.
Henderson obtained his
B.Sc.,
M.Sc.(nutrition) and
Ph.D.(breeding) degrees at
