Question

events of diplotene stage

Answer 1

Answer :-

The events that occur in the "Diplotene" stage are as follows :-

• In the "Diplotene" stage, the paired chromosomes begin to get separated from each other.

• While getting separated, the homologous chromosomes remain united at the points of interchange of "Chismata".

• "Chiasma" are formed as the result of crossing over in the Diplotene stage.

• With the progression of diplotene, the nuclear membrane gets disorganized and the nucleolus disappears.

Extra Information :-

~~~~~~~~~~~~~~~~

• The points where two of the four chromatids cross each other are known as "Chiasmata".

• In meiosis, chiasma formation takes place in the Diplotene stage.

• P.M.C. (Pollen Mother Cell) is considered as the best structure to demonstrate "Chiasmata".
