Yeah, but what if you breed the quirks across multiple generations.

You have someone like Shoto who got a quirk from his mom and another from his dad, and they have a child with someone else who has a quirk from her mother and one from her dad. That child could then potentially have 4 quirks. And the next generation could have 8, and so on.

However, we know children aren't guaranteed to have their parents quirk. I believe they implied Endeavor had several kids before getting "the result he wanted" with Shoto. So those other kids probably only had one of the two quirks. And of course Deku didn't get his mother's quirk.

So the odds of that grandchild having all 4 quirks or the great grandchild having all 8 is probably highly unlikely.
