(d) Chromatids in a cell during Anaphase II if Human cells normally have 46 chromosomes. What is the number of.... WebApr 11, 2024 · Complete answer: In meiosis I or reductional division, prophase I is divided into five stages: leptotene, zygotene, pachytene, diplotene, and diakinesis. In the zygotene stage, the homologous chromosomes or non-sister chromatids pair up to become bivalents or tetrads. It is also known as zygonema.
