Hi I recently spoke to a history professor and he has me confused. This professor told me that gynocologists told him that there is a 5% possibility that every child who is born has a father who is not his mother's husband. Ie his real father is someone other than his purported father.

Is this true? Are there any gynocologsits who can corroborate or dismiss this?

2)Also, so does this mean that over the length of 20 generations, a child will be born to a different father than the supposed "real" father or am I missing a factor in the formula? I just assumed 5% X 20 = 100% chance of wrong father....

If I am correct in my assumptions then for example, the Danish royal family who have been around for over 100 years will have had "fake" sons, since they have over 30 generations?

Please let me know. Am I missing something in my calculations? I was never good at statistics or maths.
