Question

You are given 13 meiotic divisions. From these division how many seeds how many seeds you can form? How many pollen grain will be wasted?

• A. No. of seed - 13, No. of wasted pollen grain -13
• B. No. of seed - 10, No. of wasted pollen grain - 2
• C. No. of seed - 2, No. of wasted pollen grain - 10
• D. No. of seed - 52, No. of wasted pollen grain - 52

Answer 1

Answer: (B)

No. of seed - 10, No. of wasted pollen grain - 2

If total 13 meiotoc divisions are given,

In gynoecium 10 meiotic divisions=10 eggs.

In anther 3 meiotic divisions=3×4=12 pollen grains.

Hence 10 egg+10 pollens=10 seeds.

12–10=2 pollens wasted.

So, the correct option is 'Option B'.
