Correct Matching
| Term | Association | Details |
|---|---|---|
| R.S. (Recurrent Selection) | Hull (d) | Developed by Hull (1945) to improve GCA; uses additive gene action |
| R.R.S. (Reciprocal Recurrent Selection) | Comstock (e) | Developed by Comstock et al. (1949); improves both GCA and SCA; suitable for poultry |
| Phenotype (P) | G + E (b) | P = G + E (Genotypic value + Environmental deviation) |
| Random drift | Small population (c) | Dispersive force; operates only in small populations; Sewall Wright effect |
| Repeatability | Upper limit of heritability (a) | r ≥ h²; r = (VG + EP)/VP |
