Calculating Fitness from Selection Coefficient
If coefficient of selection is 0.1, then find out fitness-
- 0.1
- 0.9 — Correct Answer
- 0.2
- 0.01
Explanation:
Correct Answer: 0.9
Formula: Fitness (F) = 1 − S, where S = Coefficient of selection.
If S = 0.1, then F = 1 − 0.1 = 0.9
Fitness — Key Concepts
| Feature | Detail |
|---|---|
| Formula | F = 1 − S (or 1 − L) |
| Range of F | 0 to 1 |
| Range of S | 0 to 1 |
| Lethal gene | S = 1, F = 0 (genotype does not contribute to next generation) |
| Neutral gene | S = 0, F = 1 (no selection against it) |
Example Calculations
- S = 0.1 → F = 0.9 ✓
- S = 0.5 → F = 0.5
- S = 1.0 → F = 0 (lethal)
