There are many explainations.
Recessive traits tend not to be passed down to immediate children.
Things like alergies are very environment dependant: witness parents who refused to expose their young kids to peanuts, in an attempt to avoid allergic response.
Nutrition in youth matters alot to how healthy you are.
A combination of your parent's genes could have given you a less.. broken.. immune system than either of them. Complex things like immune systems are complex -- there isn't a gene that says 'your immune system is Level 30'.
