What Role Does Inbreeding Play in Genetic Base Changes?

John Cole

April 3, 2025

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.
