Could you tell me what happens in recessive disorders?

Depends: I am guessing that you want to understand the action of a recessive gene. Such a gene requires two copies to make a change. Eye color is a good example. Brown is dominant and if you get one brown and one blue gene your eyes will be brown. You need to get two blue genes, one from each parent, to have blue eyes.
