This module is organized in four sections. The first section focuses on best linear unbiased prediction (BLUP) of breeding values using a numerical relationship matrix, called the A matrix. This matrix is usually derived from pedigrees of individuals. The relationships are sometimes called additive genetic covariances. The second section focuses on incorporation of markers in models and the various approaches to marker aided selection we have introduced in previous modules. The third section addresses a key issue related to the use of markers for selection, namely, how missing genotypes are inferred or imputed so that breeding values can be calculated. The final section focuses on the realized genetic matrix for G-BLUP. The genetic relationship matrix based on the markers is called the G matrix, and BLUP analysis based on the G matrix is called G-BLUP.
