Detailed explanation-1: -The chiasmata is the point where two homologus non-sister chromatids exchange genetic material during crossing over. It becomes visible at the diplotene stage of prophase I. It links homologous chromosomes together till anaphase I and gets separated. So the correct answer is ‘Anaphase I’.

Detailed explanation-2: -The chiasma is a structure that forms between a pair of homologous chromosomes by crossover recombination and physically links the homologous chromosomes during meiosis.

Detailed explanation-3: -Chiasmata is the region of crossing over between two homologous chromosomes during Prophase I of meiosis.

Detailed explanation-4: -chiasmata) is the point of contact, the physical link, between two (non-sister) 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.

Detailed explanation-5: -Chiasmata represents the site of crossing over. It is the point at which two homologous non-sister chromatids exchange genetic material.
