Use GEBV Blend when you need to blend a genomic estimated breeding value and a pedigree estimated breeding value using a weighted average. Enter Genomic EBV, Genomic weight, and Pedigree EBV using the definitions and units below so the result can be reproduced.

Genomic EBV

Signed genomic estimated breeding value.

Genomic weight

Weight given to the genomic component.

Pedigree EBV

Signed pedigree-based estimated breeding value.

The published tool contract uses this rule: Blend a genomic estimated breeding value and a pedigree estimated breeding value using a weighted average.

GEBV

The calculated gebv.

The output is an estimate tied to the stated model and coefficients; it is not a direct measurement and should retain that label when reported. Genomic weight must remain between 0 and 1.

Retain the original Genomic EBV, Genomic weight, and Pedigree EBV values and their units alongside the result. EBV Accuracy is useful when you instead need to convert an estimated breeding value reliability into the accuracy correlation as the square root of the reliability. Breeding Value EBV provides another view by helping you estimate an individual breeding value as heritability times the signed phenotype deviation from the population mean.

• EBV Accuracy

  Convert an estimated breeding value reliability into the accuracy correlation as the square root of the reliability.

• Breeding Value EBV

  Estimate an individual breeding value as heritability times the signed phenotype deviation from the population mean.

• VanRaden Genomic Relationship

  Calculate one off-diagonal genomic relationship using VanRaden's first-method scaling: the cross-product of centered marker genotypes divided by twice the sum of p(1−p) across markers. Negative estimates are possible after centering.
