Use this population- or quantitative-genetics calculation when genotype counts, variance components, pedigree relationships, and ploidy follow the definitions assumed by the tool.

Heritability

A finite measured or assumed value from 0 through 1.

Phenotype deviation

Signed deviation of the phenotype from the population mean.

The implementation follows this calculation rule: Estimate an individual breeding value as heritability times the signed phenotype deviation from the population mean.

Estimated breeding value

The calculated estimated breeding value.

Allele frequencies and genetic parameters describe the sampled population and model. Population structure, relatedness, selection, genotyping error, non-random mating, environmental covariance, and omitted variance components can bias interpretation. The output is explicitly an estimate or proxy; preserve that label when reporting it.

Inspect genotype counts and Hardy–Weinberg diagnostics, or fit a pedigree/genomic mixed model when individual records are available. Confidence intervals and replication across populations are more informative than a point estimate alone.

• EBV Accuracy

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

• Response To Selection

  Compute the breeder's equation response to selection as heritability times the signed selection differential.

• GEBV Blend

  Blend a genomic estimated breeding value and a pedigree estimated breeding value using a weighted average.
