Class 12 Biology Reproduction Sexual reproduction in Flowering Plants
The post-fertilization change involves
(a)
Haploid gametic maturation
(b)
Introduction of centrioles in the ovum
(c)
Inhibition of Meiosis-II
(d)
Formation of vitelline membrane
Correct answer: (a)
Solution:
- After meiosis 1 secondary oocyte initiates meiosis 2.
- The process of meiosis 2 is halted at the metaphase II stage until fertilization occurs.
- Meiosis 2 is completed only if fertilization takes place leading to the formation of a fertilized mature ovum and the second polar body.
- Thus the correct answer is option A.
