Question

How many reductional divisions are important for creat 100 seeds of wheat? Why only 25 egg participate in division?

Answer 1

• So total number of meiosis needed to produce x seeds = x + x/4.
• To produce 100 pollen, only 25 meiotic divisions are required and to produce 100 eggs, 100 meiotic divisions are required. Therefore, a total of 125 meiotic divisions are required to produce 100 wheat grains.
• one meiotic division is required for the formation of one ooshere (female gamete or egg). Pollen grains (microspores) are produced in the anther. ... Each microspore mother cell undergoes meiosis to form 4 haploid micropores. Each microspore (pollen grain ) develops into male gametophyte that produces male gamete.
