Q. No.Which of the following is not a feature of diakinesis stage of prophase I of meiosis I?
1.
Terminalization of chiasmata
2.
Meiotic spindle assembling to prepare separation of homologues
3.
Decondensation of the chromatin
4.
NEBD and disappearance of nucleolus
Meiosis results in the formation of:
1. Two genetically identical diploid cells
2. Two genetically non identical diploid cells
3. Four genetically identical haploid cells
4. Four genetically non identical haploid cells
Crossing over or recombination can be defined as:
| 1. | exchange of segments between sister chromatids of homologous chromosomes |
| 2. | exchange of segments between non sister chromatids of homologous chromosomes |
| 3. | exchange of segments between sister chromatids of heterologous chromosomes |
| 4. | exchange of segments between non sister chromatids of heterologous chromosomes |
Identify the stage of meiotic cell division shown in the given diagram:
| 1. | Anaphase I | 2. | Anaphase II |
| 3. | Telophase I | 4. | Telophase II |
The beginning of diplotene is recognized by:
| I: | dissolution of the synaptonemal complex |
| II: | the tendency of recombined homologues of bivalents to separate |
| III: | tetrads becoming clearly visible |
| 1. | Only I and II | 2. | Only I and III |
| 3. | Only II and III | 4. | I, II, and III |
During anaphase I of meiosis
1. Homologous chromosomes separate
2. Non-homologous autosomes separate
3. Sister chromatids separate
4. Non-sister chromatids separate
During what phase in the cell cycle would you find the most DNA per cell?
| 1. G1 | 2. G2 |
| 3. S | 4. Prophase II |
The phase of the cell cycle that is expected to be the most variable in duration in different types of cells in an animal will be:
| 1. G1 | 2. S |
| 3. G2 | 4. M |
Which stage of meiosis is shown in the diagram given below?
| 1. | Metaphase I | 2. | Metaphase II |
| 3. | Anaphase I | 4. | Anaphase II |
