During meiosis I and II, the original nucleus divides into four nuclei, each having half the original number of chromosomes.
In humans:
Meiosis I separates the pairs of homologous chromosomes from each other. Each of the two resulting cells has 23 double-stranded chromosomes and is haploid.
Meiosis II separates the sister chromatids of each chromosome from each other, pulling them apart at the centromeres and moving them into two separate nuclei. Each of the resulting cells has 23 single-stranded chromosomes (back in the form of chromatin) and is haploid. These final cells are the gametes.

If physique might have long gone basically by meiosis then very quicly all of the genetic counsel might have long gone lost and life could have been ceased to proceed to exist. If there might have basically 12 amino acids then the proteins contemporary in our bodies could have been some others. Wether those could have been sufficient for all times or not.
