Question

separation of paired homologous chromosomes begins in which stage

Answer 1

In meiosis1, (at the metaphase stage),
the tetrads(bivalent) line themselves in a equatorial plate .And during anaphase1 of meiosis1 , centromeres break down and homologous chromosomes aparts towards opposite poles resulting in the segregation of genes into the two gametes.But remember that in anaphase1 ,sister chromatids remain intact with centromeres(doesn't splits) while in meiosis2(anaphase) , centromere splits.

Answer 2

The separation of paired chromosomes occurs with the stage anaphase.  

Explanation:

• Most of the cells of our body divide to form new cell. This is signalled and controlled by certain cycle of the cell namely the cell cycle.  

• The cell cycle takes place for both somatic cells and germ cells. When the division takes place in the somatic cells it is termed as Mitosis and when it takes place in the germ cells it is termed as meiosis.  

• In both the chromosome separation takes place in the anaphase.
