Is it really "inheritable" if you don't have it?

Yeah. That's why people can be carriers for hereditary diseases, but they don't actually have the disease.

That’s generally due to recessive genes and not due to a mutation in the cell generations immediately before your gonads (though that too is possible).

Epigenetics.
You may have a trait or mutation that doesn't express itself, but your kids my find themselves in the right behavioral or environmental situation it does.

Its interesting for example how the emergence of epigenetic modifictions can affet both cognitive and endocrinological function. The amount of dopamine recepetors being deactivated during signal transmssion has been correlated with lower IQ test scores, but research into the exact modualtory mechanisms of epigenetics are still being studied. Lactose intolerance is another ntoaable case of methylation during ontogenic development.

It's inheritable in that the person born with it can pass it down. You can't really mutate post birth to have a genetic condition; if you have the condition you were born with it.
