4. Diad
Bivalent is clearly visible at which stage?
| 1. | Pachytene |
| 2. | Leptotene |
| 3. | Zygotene |

| 3. | Pachytene |
| 4. | Both A and B |
The appearance of recombination nodule is a characteristic feature of
1. Pachytene
2. Zygotene
3. Diplotene
4. Diakinesis
Recombination nodules are
| 1. | Sites over sister chromatids |
| 2. | Sites over non-sister chromatids |
| 3. | Sites over homologous chromosomes |
| 4. | Sites over non-homologous chromosomes |
Which of the following is an enzyme-mediated process?
1. Crossing over
2. Synapsis
3. Leptotene
4. Both A and B
Recombination of genetic material occurs
| 1. | Because of synapsis |
| 2. | Because of crossing over |
| 3. | Because of termination of chiasmata |
| 4. | Because of X Shaped structure |
Recombination completion leads to
| 1. | Chromosomes attached to each other at the centromere |
| 2. | Chromosomes attached to each other at sites of crossing over in the sister chromatids |
| 3. | Chromosomes linked at the sites of crossing over |
| 4. | Both A and C |
Recombination completes in
| 1. | The end of pachytene |
| 2. | Just before the end of pachytene |
| 3. | the end of midphase of pachytene |
| 4. | End of zygotene |
The dissolution of the synaptonemal complex is the recognition event of
| 1. | Ending of pachytene |
| 2. | Beginning of diplotene |
| 3. | Beginning of Diakinesis |
| 4. | Ending of Diplotene |
