Question

Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A) : Biostatistics is essential in Animal Breeding experiments.
Reason (R) : Statistical tools help in separating genetic variation from environmental variation. In the light of the above statements, choose the most appropriate answer from the options given below:

• A. Both (A) and (R) are correct and (R) is the correct explanation of (A).
• B. Both (A) and (R) are correct but (R) is NOT the correct explanation of (A).
• C. (A) is correct but (R) is incorrect.
• D. (A) is incorrect but (R) is correct.

Hint:

Biostatistics = Tool to separate genetic vs environmental effects

Answer 1

The Correct Option is A

Concept:
Biostatistics plays a vital role in analyzing biological data, especially in animal breeding where both genetic and environmental factors influence traits.

Step 1: Understanding Assertion (A)

• Animal breeding experiments generate large datasets.
• Accurate analysis is required for selection decisions. Thus, Assertion is correct.

Step 2: Understanding Reason (R)

• Phenotypic variation = Genetic + Environmental variation.
• Statistical tools (ANOVA, regression) separate these components. Thus, Reason is correct.

Step 3: Logical Connection

• Since separating these variations is essential for breeding decisions,
• biostatistics becomes necessary. Thus, Reason correctly explains Assertion. Final Conclusion: \[ \boxed{\text{Option (A)}} \]
