Relationship Between Inbreeding Coefficient and Coefficient of Relationship
The value of inbreeding coefficient (Fx) is always ________ of coefficient of relationship (Rxy).
- 2 times
- 4 times
- Square root
- Half — Correct Answer
Explanation:
Correct Answer: Half
Fx = ½ × Rxy, i.e., the inbreeding coefficient is always half of the coefficient of relationship.
Verification with Examples
| Mating | Rxy | Fx (= ½ Rxy) |
|---|---|---|
| Parent-offspring / Full-sib mating | 0.50 (50%) | 0.25 (25%) |
| Half-sib / Double first cousin mating | 0.25 (25%) | 0.125 (12.5%) |
| Single first cousin mating | 0.125 (12.5%) | 0.0625 (6.25%) |
