Ah, while that does make logical sense, The Musk did make things interesting.
Canon states that if you throw an animal into the spring of drowned girl and lock it, the children inherit traits from the original animal.
So, if Ranma got pregnant, 3 things could happen.
1, there is no effect and the children are normal.
2, due to being male human, the children end up a bit more masculine, or some other odd thing that leans more male.
3, they inherit something else animalistic in Ranma's past... minimally Either monkey (That monkey DID look a lot like Ranma... is Ranma descendent from musk? Could explain some things...) cat (while not a possession, SOMETHING went wrong with that, either cat dna, or some weird brain thing.) or another guess.
And lets go further, lets say we lock Shampoo, then throw her into the spring of drowned girl, then lock her again, does her daughters end up as catgirls? O_o
So while the curse doesn't transfer, canon says the offspring do carry traits if the circumstances are right.
What of males? What if you throw one animal into the spring of drowned man and the other into the girl one? Can you make hybrid animals? O_O

Sure a hereditary curse would count but that isn't the only way a parent being cursed could impact the kids.
Right... I only really know children that it affects them that way, plus the ones where they need to hide the curse... hold on, there's a deviantart comic...

"Oh no! What haz happened? As you cats would say." Akane asked, horrified.
"Cats do not speak that way!" Luna yelled.
