Semi-conservation replication describes the mechanism of DNA replication in all known cells. This process is known as semi-conservation because two copies of the original DNA molecule are produced. Each copy contains one original strand and one newly-synthesized strand.
DNA is passed down to the next generation in big chunks called: Chromosomes.
Every generation, each parent passes half their chromosomes to their child. If nothing happened to the chromosomes between generations, then there would be around a 1 in 8 change that you would get no DNA from a great, great, great, great grandparent.
What most people forget, through, is that our chromosomes get mixed and matched before they are passed on. It is because of this "recombination" that your great, great, great grandparent's DNA is almost cetainly still lurking in yours.
