- 1-a, 2-c, 3-e, 4-b, 5-d
- 1-c, 2-a, 3-e, 4-b, 5-d — Correct Answer
- 1-c, 2-a, 3-b, 4-e, 5-d
- 1-c, 2-d, 3-e, 4-b, 5-a
Explanation:
Correct Answer: 1-c, 2-a, 3-e, 4-b, 5-d
Correct Matching
| Breeding System | Match | Key Point |
|---|---|---|
| Close breeding (1-c) | More intensive form of inbreeding | Parent-offspring, full-sib mating; Rxy = 0.50; Fx = 0.25 |
| Line breeding (2-a) | Less intensive form of inbreeding | Half-sib, cousin, grandparent-grandoffspring mating; Rxy = 0.25; Fx = 0.125 |
| Species hybridization (3-e) | Farthest form of outbreeding | Mating between different species; e.g., Mule (Mare × Jack), Liger (Lion × Tiger) |
| Out-crossing (4-b) | Simplest form of outbreeding | Unrelated animals of the same breed; progeny = outcross |
| Cross breeding (5-d) | Breed complementation | Combines good qualities of two breeds; uses heterosis; evolves new breeds |
Examples of Species Hybridization
- Mule: Mare × Jack (donkey)
- Hinny: Stallion × Jennet
- Liger: Male lion × Female tiger
- Tigon: Male tiger × Female lion
- Cattalo: American buffalo bull × Exotic cattle
- Zonkey: Zebra × Donkey
