Which genetic parameter describes the correlation between an animal's performance for the same trait measured on different occasions?
Correct answer: B. Repeatability
- A. Heritability
- B. Repeatability
- C. Genetic correlation
- D. Phenotypic variance
Explanation
Repeatability is the correlation between repeated records of the same trait in an individual. Heritability concerns genetic contribution to phenotypic differences, while genetic correlation relates two different traits.
