1. Chromosomes interlockings occur during the late zygotene.

2. Zygotene is characterized by the active and specific pairing( synapsis ) of homologous chromosomes leading to the formation of a haploid number of bivalents.

3. The karyotype of Nelumbo nucifera during meiosis zygotene was established in this study, which would help the studies of meiosis and molecular cytogenetics in lotus.

4. Prophase may be divided into successive stages termed leptotene, zygotene, pachytene, diplotene, and diakinesis .

5. The sensitivity degree of spermatiferous cells to the change of temperature are, in turn, spermatid, zygotene primary spermatocytes and type A spermatogonia.

6. In wheat, during meiotic division, H3 phosphorylation initiated in special domains at the transition from leptotene to zygotene.
