Q.

Assertion: Mendel was successful in his hybridization experiments.
Reason: Garden pea proved as an ideal experimental material.

1 Both Assertion and Reason are correct and Reason is the correct explanation of Assertion.  
2 Both Assertion and Reason are correct but Reason is not the correct explanation of Assertion.  
3 Assertion is true but Reason is false.  
4 Assertion is false but Reason is true.  

Ans.

(1)

The pea plant which Mendel chose for conducting experiments, is most ideal for controlled breeding, since it can easily be subjected to cross pollination. He identified very clear contrasting characters in the pea plants. Thus, both assertion and reason are correct and reason is the correct explanation of the assertion.
