Question

How many meiotic divisions are required to produce 40 seeds in a Tomato fruit?​

Answer 1

Answer:one meiotic division of Megaspore mother cell leads to formation of one egg cell. So 300 egg cells are formed from 300 meiotic division. But one meiotic division of sperm mother cell leads to formation of four haploid cells. So 300 functional gametes will be formed by 300/4= 75.

So, total meiotic division required is 375.

Answer 2

Answer:

One egg is produced by the meiosis of egg mother cell. So, the total number of seeds is equal to the number of meiotic divisions in the female. It is also known that each pollen mother cells divide by meiosis to form four haploid pollen grains. Out of which, only one pollen grain participates in fertilizations. Therefore, 1/4 of the total number of seeds is equal to the number of meiotic divisions in a male. Now, total number of divisions = (50/4)+50 = 12.5 + 50 = 62.5. The divisions can not occur in decimals.
