Any biological child of yours will have 23 chromosomes of yours and 23 from the other parent. The copying process is almost perfect, but a few tiny errors are made - like 5 typos total in a set of 23 books, per generation...
If you have the exact same bunch of typos on a chromosome as somebody else, you have a shared ancestor.
You also have mitochondrial DNA from your mother, who got it from her mother, who got it from her mother

The ancestor has an identical gene as their offspring. The gene was passed down by the ancestor.
