Correct Matching
| Term | Association |
|---|---|
| R.S. (Regular/Recurrent Selection) | Associated with Hull (Shull) — term heterosis coined by G.H. Shull |
| R.R.S. (Reciprocal Recurrent Selection) | Given by Comstock; improves both GCA and SCA; more suitable for poultry |
| Phenotype | P = G + E (Genotypic value + Environmental deviation) |
| Random drift | Operates in small population only (dispersive force) |
| Repeatability | Upper limit of heritability (r ≥ h²) |
