What cuases allergies in the first generation that have them?

[Guest guest]

Hi all,

I have been thinking about the genetic side of allergies and how people that

suffer from them are more likely to pass them on to their children. Would it

not be interesting to find out what caused them in that generation in the first

place? For example, my husband's parents and grandparents had no allergies on

either side of the family yet he has 13 allergies. How can this be? There must

be more than that and I think that genes are just half the story here,

something triggers them and I think we all know what that something could be.
