Given below are two statements:
| Statement I: | Mendel studied seven pairs of contrasting traits in pea plants and proposed the Laws of Inheritance |

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).
| Assertion (A): | Mendel's law of Independent assortment does not hold good for the genes that are located closely on the same chromosome. |
| Reason (R): | Closely located genes assort independently. |
In the light of the above statements, choose the correct answer from the options given below:
| 1. | (A) is False, (R) is True. |
| 2. | Both (A) and (R) are True and (R) correctly explains (A). |
| 3. | Both (A) and (R) are True and (R) does not correctly explain (A). |
| 4. | (A) is True, (R) is False. |
