If a geneticist uses the blind approach for sequencing the whole genome of an organism, followed by assignment of function to different segments, the methodology adopted by him is called as:
| 1. | Bioinformatics | 2. | Sequence annotation |
| 3. | Gene mapping | 4. | Expressed sequence tags |
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 but (R) is True. |
| 2. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 3. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
| 4. | (A) is True but (R) is False. |
