Question

No. of meiotic divisions required to produce 200/400 seeds of pea would be

A.200/400

B.400/800

C.300/600

D.250/500

Answer 1

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.

It has a formula, x seeds=x+x/4 meiotic divisions
So for 200 seeds, 200+200/4=250 meiotic division needed
