Answer 3

Recessive means that it isn't going to go into effect if there is a dominant trait above it, Dominate traits almost always show instead. So, although your question was kind of hard to understand, I assume you we're being asked why the disease didn't appear in the offspring, and it's because it's a recessive trait.
