Are you 50% related to your siblings?

While we do get 50% of our DNA from each parent, we don't get the same 50% as our siblings. In general, there is about a 50% overlap between the DNA you got from your mom and the DNA your brother or sister got from that same mom. So you and your sibling share 50% of 50% of mom's DNA or 25%.
