How to calculate the probability that a mutation occurred? According to the internet, there is a 7% chance that two brown-eyed parents will have a green-eyed child. However, Dominance says that it is impossible for this to happen. Is the internet correct? If so, how is that 7% chance calculated? source: <

Sadly the site you referenced is not scientific. There is no scientific basis for a claim that "there is a 7% chance that two brown-eyed parents will have a green-eyed child". It is correct that multiple genes determine eye color, and the effects of some depend on the versions (alleles) of the other genes present, so predicting eye color is not as straightforward as it might seem.
