Question

In which sub phase of prophase in meiosis 1 does d chiasmata actually form? plz do answer.

Answer 1

The chiasmata become visible during the diplotene stage of prophase I of meiosis, but the actual "crossing-over" of genetic material is thought to occur during the previous pachytene stage. When each tetrad, which is composed of two pairs of sister chromatids, begins to split, the only points of contact are at the chiasmata.
