explain about prophase ll metaphase ll Anaphase ll and Telophase ll
Answers
Answer:
Prophase ll :
Meiosis ll is initiated immediately after cytokinesis usually before the chromosomes have fully elongated. In contrast to meiosis l, meiosis ll resembles a normal mitosis. The nuclear membrane disappears by the end of prophase ll. The chromosomes again become compact.
Metaphase ll :
At this stage the chromosomes align at the equator and the microtubules from opposite poles of the spindle get attached to the kinetochores of sister chromatids.
Anaphase ll :
It begins with the simultaneous splitting of the centromere of each chromosome allowing them to move toward opposite poles of the cells by shortening of microtubules attached to kinetochores.
Telophase ll :
Meiosis ends with telophase ll, in which the two groups of chromosomes once again get enclosed by a nuclear envelope;cytokinesis follows resulting in the formation of tetrad of cells i.e., four haploid daughter cells.
Explanation:
phrophrase 2
chromosomes condense and the nuclear envelope breaks down
Metaphase 2
the chromosomes line up individually along the metaphase plate.
Anaphase 2
The centromeres separate and the sister chromatids
Telephase 2
the chromosomes reach opposite poles, cytokinesis occurs
