@Omojoze That's how it works with MS though, they're automatically granted the ability to use three techniques, and they have to develop them on their own obviously, but they already have them. Amaterasu is a Uchiha KG that grants them the ability to create inextinguishable black flames, so the fire release must be genetic. Also, they do have to learn hiden, but they're born with kekkei genkai. Haku was seen using it as a child when he had no one to teach him, even Zabuza couldn't have taught him it but he developed it on his own. Chakra was said to be inheritable and determined by your genetics a million times throughout the series. It's on the Chakra page itself too. Kaguya's sons were born with chakra because she consumed the fruit, she passed it on to her sons, and Hagoromo and Hamura passed it on to their children and descendants. Tobirama was able to determine that Karin was an Uzumaki due to her chakra signature, which means relatives have similar chakra signatures, so genetics plays a pivotal role in chakra. Also, it doesn't matter if that's not how it works irl, in Naruto, you inherit half of your parents. That was made clear by Hagoromo, each of his sons inherited half of his chakra.
