Question

Explain about prophase ll metaphase ll Anaphase ll and Telophase ll​​

Answer 1

• Prophase II is the phase that follows after meiosis I, or after interkinesis if present. If interkinesis takes place, the nuclear envelope and the nucleolus disintegrate during prophase II. The chromosomes are condensed. The centrosomes replicate and move towards the opposite poles.

• Metaphase II is the second stage in meiosis II. The cell is in metaphase II when the chromosomes align themselves along the metaphase plate through the facilitation of the spindle fibers. The spindle fibers are now attached to the two kinetochores contained in the centromere of each chromosome.

• Anaphase II is the stage when sister chromatids of every chromosome separate and begin to move towards the opposite ends of the cell. The separation and the movement is due to the shortening of the kinetochore microtubules. Anaphase II precedes telophase II. Meiotic anaphase II is similar to the anaphase in mitosis.

• Telophase II is the stage in meiosis II that follows after anaphase II. This will then be followed by cytokinesis, wherein each of the two cells produced from meiosis I will give rise to two daughter cells, resulting in a total of four genetically dissimilar haploid cells. The chromosomes de-condense and lengthen.
