Difference between Fertile eggs and Infertile eggs

Question
Is it that infertile eggs dont have the genetic material and they are not made from fertile eggs?
Can one be called a pure vegetarian if he eats eggs only?

Answer
I don't know much about genetics but if an egg has been laid un-fertilised it will never hatch. Of course they have genetic material in them, all eggs (whether human, dog or cat, or chicken) have genetic material in them. If you are worried that it is cruel to eat a chickens egg as it lays it because it wants a baby, you are wrong, it isn't, chickens lay tonnes of eggs that would just build up messily if left.
I am definately not a vegetarian, I believe in organic and free range meat which has had a good life- I don't believe in vegetarianism, but if I was to become one, I would have no problem with eating the eggs.
