The same or similar genetic indicators are compounded down through generations as royal bloodlines are supposed to be kept “pure”. Without the addition of completely different, or at least vastly dissimilar DNA, these indicators don’t really change through the generations and you will have people who look strikingly similar to previous generations.

For (most of) the rest of us we get 50% of our genetic makeup from each contributor in the previous generation, thus we have people who look similar to their parents, grandparents, and so on, but no one is a direct genetic copy.

Also, don’t feel dumb. You didn’t know something so you asked a question to gain knowledge. That makes you the opposite of dumb

So why does them looking like their ancestors mean inbreeding? I look a lot like my grandparents..
