What Role Does Inbreeding Play in Genetic Base Changes?

April 3, 2025

Genetic base changes include both corrections for observed genetic trends in the population and adjustments to account for future inbreeding. After the April 2025 base change, observed changes in Predicted Transmitting Abilities (PTAs) for individual animals may not match the base change values as closely as they have in the past. This is not due to any errors in the evaluation. It reflects Expected Future Inbreeding (EFI) changes in the population that are larger than they’ve been in the past.
