I've had a paternity test done. I know they are mine. Its just a really lucky coincidence. I'm glad my kids all have blue eyes and blonde hair.
I don't know your situation, but a paternity test can come out showing you as the father even if the real father is your father or brother. The only way some labs would test for that is if they were specifically asked to test for those possibilities. Otherwise they may only look for markers that any immediate male relative could share with you. I'm hoping you don't have a dad or brother with brown/green eyes.
I would call that a bit paranoid.
Statistically speaking, it's not paranoid at all. In fact, it's probably mathematically more likely.
Only very specific combinations of blue-eyed genetics can even give the possibility of dark-eyed children. If my math isn't too rusty the probability of two randomly selected blue-eyed people having the right combination of genes to even have the possibility of producing dark-eyed children is about 1.7%. The probability of their children having dark eyes is 25%. The probability of them having three children, all with dark eyes, is around 1.5%.
To put that into perspective, if you had 4,000 couples all with blue eyes, and each couple had three children, only one of those 4,000 couples would have three dark-eyed children.
