Question

Match List I with List II 

Choose the correct answer from the options given below: 
 

• A. A - I, B - III, C - IV, D - II
• B. A - I, B - II, C - III, D - IV
• C. A - IV, B - III, C - II, D - I
• D. A - II, B - III, C - I, D - IV

Hint:

Breeding Systems:
Inbreeding = Related animals.
Outbreeding = Unrelated animals.
Outcrossing = Unrelated animals within SAME breed.
Crossbreeding = Animals from DIFFERENT breeds.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Systems of animal mating: inbreeding vs outbreeding systems and their genetic definitions.

Step 2: Detailed Explanation:
Matching animal breeding systems in List I with definitions in List II:
- A. Outbreeding: Mating of I. Unrelated animals (less closely related than the breed average).
- B. Inbreeding: Mating of III. Related animals (more closely related than the breed average, e.g., sire-daughter, brother-sister).
- C. Outcrossing: Mating of IV. Unrelated animals within same pure breed having no common ancestors in the pedigree for 4 to 6 generations.
- D. Crossbreeding: Mating of II. Animals from different established breeds (e.g., Holstein $\times$ Sahiwal).
Matching sequence: A - I, B - III, C - IV, D - II.

Step 3: Final Answer:
Hence, the correct matching is A - I, B - III, C - IV, D - II, matching option (A).
