I just recalled something. Remember how the Musk dinasty breeds? If the
curse can't be inherited, how can the children be human? If the curse can
be inheritable, 99% of their population would be female.

That's not a question of the curse being inheritable but the form
being inheritable.  However, the Musk Dynasty also indicates that
that the offspring is slightly influenced by the nature of the cursed
parent's alternate form.  Thus, Shampoo's daughter might look like
the Puma sisters, Ranma's son might be one of those Bishonen guys,
And I'm sure Akari would love a son or daughter with a cute little
curly tail.

That's the wrong way around.  The Musk Dynasty gets some traits of the
parent's uncursed form when they have children in the cursed form.  Your
ideas all have the parent's cursed form giving traits to children that they
have when in uncursed form.
