Assertion(A): | Human ancestors never used their tails so that tail expression gene has disappeared in them. |
Reason(R): | Lamarck's theory of evolution is popularly called theory of continuity of germplasm. |
1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). |
3. | (A) is true but (R) is false. |
4. | Both (A) and (R) are false. |
Assertion(A): | According to Lamarck the rate and survival of organisms are different due to variations. |
Reason(R): | Lamarck gave the theory of pangenesis. |
1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). |
3. | (A) is true but (R) is false. |
4. | Both (A) and (R) are false. |
Assertion(A): | Australian marsupials can be taken as an example of adaptive radiation. |
Reason(R): | A number of marsupials, evolved from an ancestral stock, but all within the Australian island continent. |
1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). |
3. | (A) is true but (R) is false. |
4. | Both (A) and (R) are false. |
Assertion(A): | Evolution is not a directed process in the sense of determination. |
Reason(R): | It is stochastic process based on chance events in nature and chance mutation in the organisms. |
1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). |
3. | (A) is true but (R) is false. |
4. | Both (A) and (R) are false. |
Assertion (A): | As per Darwin, over many generations, survivors will leave more progenies. |
Reason (R): | Survivors have variations that make resource utilization better for them. |
1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
