Meiosis is when the parent (haploid) cells divides into two to create for daughter cells having half chromosome's number. This the produce sex cells or gametes - sperm for males while eggs for females. The division is in 9 stages here there is meiosis I then there is also meiosis II.
Well, I don't fully understand your question. I think I know what you're getting at though.
In a system of sexual reproduction, you have genes coming from both an egg and the sperm. Therefore, it'll only contain half the total amount of chromosomes (46 in humans). A sperm will have 23, and the egg will have the other 23. Is that what you meant why the chromosomes are cut out in pairs? If that wasn't your question, please elaborate and I'll return to answer it to the best of my capabilities.
