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.
