Well from Hagoromo and Hamura didn't inherit Tailed Beast chakra. They only recieved abilities/traits displayed by Kaguya herself. Arguably since she is the 10 tails the chakra could be the same but this was never noted by anyone and Hagoromo even absorbed her and could not sense that the chakra was the same.

So this heavily implies that tailed beast chakra is inherently different than other kinds of chakra. We have also seen that whatever abilities granted by a tailed beast are essentially borrowed powers because they are borrowing chakra. It wouldn't make sense for those powers to be passed down genetically.

Naruto though has that 6 Paths power up, which did make a fundamental change to his chakra, which means it changed the way his body produces chakra. This is much more likely to influence genetic mutations since part of chakra is based on genes, this is evident by Kabuto and the change in his chakra signature.

The mixing of Naruto's 6 paths chakra and Hinata's Hamura chakra may have been the biggest factors. I don't believe that Boruto or Himawari inherted these special chakras but partially due to them they have developed new abilities(Boruto) or develop at a faster rate(Himawari).
