Answer:

The pair of chromosomes come together in a process called synapsis which occurs in the pachytene phase of prophase 1 of meiosis

The correct answer is option (3) Chiasmata.

  • A chiasma is the point of contact, the physical link, between two chromatids belonging to homologous chromosomes.
  • At a given chiasma, an exchange of genetic material can occur between both chromatids, what is called a chromosomal crossover, but this is much more frequent during meiosis than mitosis.
  • So, Chiasmata marks the site where crossing over had  occurred.
