by an abnormal reaction to a harmless antigen in the environment. These
diseases include food allergies, hay fever, atopic dermatitis and allergic

That question is confusing. Cells obviously take from its parent cells, which means that DNA is combined from both mom and dad in a unique way. That can cause the offspring to have either the mom's or dad's eyecolor. So the "different genes" part apply to that because for each feature of the offspring it is a complex combination of mom and dad. What I don't get is the different cells. there are these things called stem cells which are basically cells that can be anything in the body when there's a need for it.
