Question

transition between zygotene and pachytene

Answer 1

Answer:

Explanation:

Both zygotene and pachytene are the sub stages of meiosis-1.

Zygotene:

  The most important event of the meiosis-1 starts in zygotene.

            Pairing of homologous chromosomes is

            called as synapsis.

Synapsis occurs in zygotene.

Pachytene:

 Pairing of homologous chromosomes is completed in Pachytene.

In this stage,Homologous chromosomes starts exchanging their segments (non-sister chromatids).This process is called as crossing over,

After Pachytene,there comes Diplotene And Diakinesis.And Prophase-1 of meiosis-1 is completed.
