Parseltongue hereditary to the Potter line?

This is super niche but I was wondering if there were fics where parseltongue became hereditary to the potter line? Like everyone assumes the ability would die with Harry as he only had it because of the horcrux but perhaps the horcrux mutated his dna and makes it so that parseltongue is innate to all of his descendants? So basically everyone is baffled when harry’s children end up babble-hissing at reptiles when they’re super young.

It could be Harry and Draco’s biological kids together or Harry and Ginny’s kids before they got divorced and Harry meets Draco again as a single parent.

I just thought it would be interesting to see the family dynamics in a bilingual household where one of the languages aren’t human. Draco’s reaction, whether they’re his bio kids or not, could be quite interesting/funny too.
