Question

You are given a total of $13$ meiotic divisions. From these division how many seeds you can form? How many pollen grain was 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 - 13, No of wasted pollen grain - 39
• D. No of seed - 13, No of wasted pollen grain - 52

Answer 1

The correct option is B No of seed - 10, No of wasted pollen grain - 2

If total 13 meiotic divisions are given, in gynoecium 10 meiotic divisions =10 eggs, in anther 3 meiotic divisions= 3x4=12 pollens, so 10 egg+ 10 pollens= 10 seeds. 12-10=2 pollens wasted.

So, the correct option is 'No of seed - 10, No of wasted pollen grain - 2'.
