| 1. | Random mating must occur. |
| 2. | The population must be infinitely large. |
| 3. | Migration must occur frequently with other populations. |
| 4. | There should be no selection for any of the genotypes. |
| Assertion (A): | Disturbance in genetic equilibrium, or Hardy-Weinberg equilibrium can be interpreted as resulting in evolution. |
| Reason (R): | This principle says that allele frequencies in a population are stable and is constant from generation to generation. |
| 1. | Both (A) and (R) are True and (R) correctly explains (A) |
| 2. | Both (A) and (R) are True but (R) does not correctly explain (A) |
| 3. | (A) is True, (R) is False |
| 4. | Both (A) and (R) are False |
