subkeys do not 'inherit' signatures; they are signed, and as such become
attached to your public key.
At any one time, you should preferably have one valid subkey. The idea is
that if need be, you can revoke a subkey because it has been compromised
(possibly law enforcement requires you to decrypt messages), without
revoking the primary key. This allows you to stay keep your web of trust,
and you simply create a new subkey.
