Question

Desynapsis or unpairing of homologous chromosomes started in which stage

Answer 1

diplotene stage.in diplotene stage synopsis of the chromosome occurs latter on In deployed stage this synapsis is broken down and homologous chromosomes separate from the bivalent and forms chiasmata of nonhomologous chromosomes

Answer 2

Desynapsis or unpairing of homologous chromosomes started in diplotene stage.

Diplotene is the fourth stage in the first meiotic prophase in gametogenesis, where chiasmata form between the chromatids of paired homologous chromosomes and crossing over occurs. The chromosomes then start to repel each other and separate longitudinally, forming loops.
