Question

Desynapsis or unpairing of homologous chromosomes started in which stage

Answer 1

This phenomenon is called recombination or crossing over. It happens in prophase 1 where the homologous chromosomes pairs up and exchange section of DNA. Chromosomal crossover is basically the exchange of genetic material between pair of homologous chromosomes non-sister chromatids that results in recombinant chromosomes during sexual reproduction.

Answer 2

The whole process occurs at the beginning of prophase.

The Desynapsis condition occurs when the chromosomes of homologous nature started to pair up with each other.

Also, it handles the association that occurs between the different stages in meiosis.

This type of system is divided prematurely in the system.

It plays a significant role in the working of the 2n gametes.
