- Individual selection — Correct Answer
- Family selection
- Pedigree selection

Individual selection (mass selection) is the simplest, most rapid, and most commonly used basis for selection in animal breeding. Animals are selected based solely on their own phenotypic records without waiting for progeny or family data.
Basis of Selection — Comprehensive Comparison
| Basis | Based on | Unique Feature | Best used for |
|---|---|---|---|
| Individual selection | Own phenotype | Simplest; most rapid; shortest generation interval | High h² traits |
| Pedigree selection | Ancestors' performance | Used before own record is available | High h² traits |
| Progeny testing | Offspring performance | Most effective and best basis; two-way selection; used for sire selection | Low h²; sex-limited traits |
| Family selection | Collateral relatives (sibs) | Includes sib selection as a special case | Low h²; carcass traits |
