I don't know wether this is what you are asking cause I don't really understand the question butt it could have something to do with the genes being recessive or dominant so when they come in pairs and you could have the two parents with one dominant(disease)and recessive(healthy) gene , the combination of the two recessive genes would give a healthy child.
