How does the alternation of meiosis and fertilization in the life cycles of sexually reproducing organisms maintain the normal chromosome count for each species?

Answer:
Simple, Meiosis reduce the chromosome number in half while fertilization doubles the chromosome number.

n=chromosome number
Meiosis = 2n (primordial germ cells) ----> n (sperm cell/egg cell/polar bodies)
Fertilization = sperm (n) + egg (n) ----> 2n (zygote)
