Q. No.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 false and (R) does not correctly explain (A). |
| 4. | (A) is true, (R) is false. |

Two genes R and Y are located very close on the chromosomal linkage map of the maize plant. When RRYY and rryy genotypes are hybridized, then F2 segregation will show:
1. higher number of the recombinant types
2. segregation in the expected 9:3:3:1 ratio
3. segregation in a 3:1 ratio
4. higher number of the parental types
