In a meiotic division, we have two phases: Meiosis I and meiosis II. So, we get a total of four haploid cells from one diploid cell. Hence, for the formation of one seed: Pollen Grain (Microsporogenesis): Four pollen grains are produced as a result of one meiotic division in a pollen sac. 4 pollen grains= 1 meiotic division 1 pollen grain= 1/4 meiotic division 50 pollen grains= 50/4 meiotic divisions Egg (Megasporogenesis): In the megasporangium, only one functional egg cell is produced, because of the degeneration of three others. 1 egg cell= 1 meiotic division 50 egg cells = 50 meiotic divisions To get the total number of meiotic divisions, we add both the aforementioned values, Total number of meiotic divisions= 50/4 +50 = 62.5 meiotic divisions.
