Which statement best describes the purpose of repeatability in performance records?

• A. It looks at the future performance of the same animal
• B. It compares performance across different animals
• C. It estimates environmental variance only
• D. It predicts market value

Answer: (A)

Repeatability measures how consistent an animal’s performance is across repeated measurements, incorporating both genetic and permanent environmental influences. Because it reflects how well one record predicts future records for the same animal, it serves as a gauge of how much a single observation can tell you about future performance. That’s why the statement describing repeatability as looking at the future performance of the same animal is the best fit. It’s not about comparing different animals, nor is it limited to environmental variance alone—genetic and permanent environmental effects are part of what repeatability captures. And while good performance can influence market value, repeatability itself is about predictability of future performance, not directly about price.
