Question

Please place the following aspects of meiosis in the order in which they occur during M-phase. Assume that the meiotic cell being described has an interkinesis stage. Number 1-7.

Segregation of sister chromatids toward opposite poles of the cell followed by cytokinesis.

Alignment of duplicated chromosomes in the center of the cell

Condensation of chromosomes in a haploid cell

Condensation of chromosomes in a diploid cell

Alignment of pairs of chromosomes along their lengths and formation of chiasmata

Alignment of paired chromosomes in the center of the cell

Segregation of paired chromosomes toward opposite poles of the cell followed by cytokinesis

Answer 1

Meiosis produces four haploid cells from a single diploid cell.

Meiosis is responsible for genetic variation in a species.

Stages of meiosis:

1. Condensation of chromosomes in a diploid cell

2. Alignment of duplicated chromosomes in the center of the cell

3. Alignment of pairs of chromosomes along their lengths and formation of chiasmata

4. Segregation of paired chromosomes toward opposite poles of the cell followed by cytokinesis

5. Condensation of chromosomes in a haploid cell

6. Alignment of paired chromosomes in the center of the cell

7. Segregation of sister chromatids toward opposite poles of the cell followed by cytokinesis.
