Diplotene

Q.

Meiosis involves:

1. A single nuclear division and a single chromosomal division

2. A single chromosomal division and two nuclear divisions

3. Two nuclear divisions and two chromosomal divisions

4. Two chromosomal divisions and a single nuclear division

Q.

Synaptonemal complex is observed during cell division in

1. Mitotic prophase

2. Mitotic telophase

3. Meiotic metaphase

4. Meiotic prophase

Q. The study of chromosomes at meiotic diplotene shows that:

1. The intimately paired chromosomes completely separate from each other
2. The pairing of homologous chromosomes which had initiated in the earlier stage is completed
3. The homologous chromosomes remain united by chiasmata
4. None of the above

Q.

Chiasmata are first seen in

1. Pachytene

2. Zygotene

3. Leptotene

4. Diplotene

Q.

The stage during which separation of the paired homologous chromosomes begins in

1. diakinesis
2. diplotene
3. zygotene
4. pachytene

Q. Crossing over occurs during the pachytene stage of prophase in meiosis, however the chiasma are visible during

1. Leptotene
2. Pachytene
3. Diplotene
4. Zygotene

Q.

Separation of homologous chromosomes is

1. Dispersion

2. Disjunction

3. Bivalent formation

4. Crossing over
