Question

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R Assertion A: Cladograms are diagrams that depict the relationships between different groups of taxa. Reason R: Cladistics analyses collection of heritable character data. 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 not correct.
• D. A is not correct but R is correct.

Hint:

Cladograms are prepared using inherited evolutionary characters.

Answer 1

The Correct Option is A

Concept:
Cladistics is a method of classification based on evolutionary relationships.
Step 1:
Cladograms are branching diagrams showing relationships among taxa. Thus Assertion A is correct.
Step 2:
Cladistics studies inherited characters shared among organisms. Thus Reason R is correct.
Step 3:
The collected heritable character data are used to prepare cladograms. Therefore R correctly explains A.
Step 4:
\[ \boxed{\text{Both A and R are correct and R explains A}} \] \[ \boxed{\text{Correct Option = (1)}} \]
