What DNA Is Passed From Father To Son?

How is DNA passed from parent to child?

One copy is inherited from their mother (via the egg) and the other from their father (via the sperm).

A sperm and an egg each contain one set of 23 chromosomes.

When the sperm fertilises the egg, two copies of each chromosome are present (and therefore two copies of each gene), and so an embryo forms..

It has been estimated that a mutation occurs about once every 500 generations, or every 15,000 years, give or take a few millennia.
