Alignment of bivalent chromosomes on the equatorial
plate and splitting of centromeres occur respectively
in which of the following stages of cell division?

1. Anaphase I and anaphase II.
2. Metaphase II and anaphase I.
3. Metaphase I and anaphase II.
4. Pachytene and telophase I.

During meiosis, the sister chromatids separate during:

(1) Anaphase II    

(2) Anaphase I     

(3) The S phase    

(4) Synapsis

These given statements are related with specific phase
of meiosis, select the unrelated statement with the
phase given below.
               Statement                              Phase
1. The homologous chromosome      –    Anaphase I
separate, while sister
chromatids remain associated
at their centromere
2. The bivalent chromosomes align   –   Metaphase I
on the equatorial plate
3. Cytokinesis follows resulting in      –  Telophase I
the formation of tetrad of cells
4. Terminalisation of chiasmata         –  Final stage
of prophase

Identify the correct matched pair.
(1) Segregation-Metaphase ll

(2) Significance of meiosis-production of genetically similar cells

(3) Exchange of genetic material- DIakinesis

(4) Anaphase ll of meiosis-Centromeric division

What is the correct sequence of the steps given here ? Also work out the process depicted in the steps.
(i) Homologous chromosomes move toward opposite poles of the cell; chromatids do not separate
(ii) Chromosomes gather together at the two poles of the cell and the nucleare membranes reform 
(iii) Homologous chromosomes pair and exchange segments 
(iv) Homologous chromosomes align on a central plate
(v) The haploid cells separate completely
(1) The correct sequence is $\mathrm{III}\to \mathrm{IV}\to \mathrm{I}\to \mathrm{II}\to \mathrm{V}$ and the process is meiosis-I

(2) The correct sequence is $\mathrm{II}\to \mathrm{I}\to \mathrm{V}\to \mathrm{IV}\to \mathrm{III}$ and the process is mitosis

(3) The correct sequence is $\mathrm{IV}\to \mathrm{I}\to \mathrm{III}\to \mathrm{II}\to \mathrm{V}$ and the process is meiosis-I

(4) the correct sequence is $\mathrm{II}\to \mathrm{V}\to \mathrm{IV}\to \mathrm{I}\to \mathrm{II}$ and the process is mitosis

Chromosome number is reduced during meiosis because the process consists of:

(1) Two cell divisions without any chromosome replication

(2) A single cell division without any chromosome replication

(3) Two cell divisions in which half of the chromosomes are destroyed

(4) Two cell divisions and only a single round of chromosome replication

Which of the following is not true for sister chromatids?

(1) They arise by replication during S phase

(2) They segregate from each other during each mitotic anaphase

(3) The usually contain identical versions of the same genetic information

(4) They segregate from each other during meiosis I
