Prophase of the mitotic division is
| 1. | Longer and more complex than prophase-l of meiosis |
| 2. | Shorter and less complex than prophase-l of meiosis |
| 3. | Longer and less complex than prophase-l of meiosis |
| 4. | Shorter and more complex than prophase-l of meiosis |
Place stages of Prophase I in correct order.
| 1. | diakinesis, diplotene, leptotene, pachytene, zygotene. |
| 2. | diplotene, leptotene, pachytene, zygotene, diakinesis. |
| 3. | leptotene, pachytene, diakinesis, diplotene, zygotene. |
| 4. | leptotene, zygotene, pachytene, diplotene, diakinesis |
| 1. | Prophase of meiosis I |
| 2. | Prophase of meiosis II |
| 3. | Anaphase of meiosis I |
| 4. | Anaphase of meiosis II |
Crossing over that results in genetic recombination in higher organisms occurs between:-
1. Non-sister chromatids of a bivalent
2. Two daughter nuclei
3. Two different bivalents
4. Sister chromatids of a bivalent
| Statement I: | Meiosis results in the reduction of chromosome number by half. |
| Statement II: | Meiosis increases the genetic variability in the population of organisms from one generation to the next. |
| 1. | Statement I is correct; Statement II is correct |
| 2. | Statement I is correct; Statement II is incorrect |
| 3. | Statement I is incorrect; Statement II is correct |
| 4. | Statement I is incorrect; Statement II is incorrect |
Synapsis occurs between:
| 1. | a male and a female gamete |
| 2. | mRNA and ribosomes |
| 3. | spindle fibres and centromere |
| 4. | two homologous chromosomes |
| 1. | chromosome uncoiling |
| 2. | DNA synthesis |
| 3. | terminalisation of chiasmata |
| 4. | cytokinesis |
The complex formed by a pair of synapsed homologous chromosomes is called:
1. Kinetochore
2. Bivalent
3. Axoneme
4. Equatorial plate
