• Diakinesis, further contraction of the bivalents, the nuclear membrane disappears
• Diplotene, shortening of the chromosomes by contraction. Interchange of chromatin between the maternal and paternal chromosomes (crossing over)
• Leptotene, the chromosomes appear as fine threads
• Mature two-nucleate pollen grains at the time of shedding. Each pollen grain possesses a tube cell and a generative cell
• Mature pollen grains, w.m. to show structure of the cell walls
• Metaphase and anaphase of the first (heterotypic) division, showing spindle threads. Two haploid sets of chromosomes are separated
• Metaphase and anaphase of the second (homeotypic) division, two mitotic figures are present
• Pachytene, complete pairing of the chromosomes
• Pollen tetrads, four nuclei are formed after the second division, each bearing the haploid number of chromosomes. Formation of cell walls
• Telophase of the first and prophase of the second division
• Uninucleate microspores after separation of daughter cells
• Zygotene, the homologous chromosomes associate in pairs. The chromosomes appear as strings of beads
