Number of meiotic divisions required to produce 200/400 seeds of pea would be
1 400/800
2 300/600
3 250/500
4 200/400
Explanation:
Number of meiotic divisions required to produce 200/400 seeds of pea would be 250/500. 200 seeds of pea would be produced from 200 pollen grains and 200 eggs. 200 pollen grains will be formed by 50 microspore mother cell while 200 eggs will be formed by 200 megaspore mother cell so 250/500.
