Answer 1

There are many genes that regulate eye color, I don't think we even know how many right now.  There can be a lot of different combinations and interactions between those genes which could pretty much make any color.  

Answer 2

well, this can happen due to the fact that the color of you eyes are determined by multiple genes.  because green eyes are a mixture of brown and blue (i think, not positive) you are able to have children with brown, blue, and green eyes.
