The coefficients of relationship of progenies produced by parent-offspring mating, full-sib mating, and half-sib mating are respectively:
Options
0.25, 0.50, 0.25
0.50, 0.25, 0.125
0.50, 0.50, 0.25 ✓
0.25, 0.25, 0.125
Correct Answer: C
Explanation in English
Correct Answer: 0.50, 0.50, 0.25
From Table 3 in the notes:
Mating Type
Coefficient of Relationship (Rxy)
Inbreeding Coefficient (Fx)
Parent-offspring
0.50 (50%)
0.25 (25%)
Full-sib
0.50 (50%)
0.25 (25%)
Half-sib
0.25 (25%)
0.125 (12.5%)
Key Rule
Inbreeding coefficient (Fx) = ½ × Coefficient of Relationship (Rxy). Parent-offspring and full-sib matings have the same coefficient of relationship (0.50) and the same inbreeding coefficient (0.25).
