Which is why Akuha's statement about it not being hereditary makes sense- it has to be through the blood, and the mother's blood doesn't come in contact with the baby's while they're in the womb
of course, for all we know, Akasha may have bitten Moka at one point to transfer the power along...
You're correct on the part that blood from the mother doesn't come into contact with the fetus but Moka could've been born as a Shinso regardless of that fact. I personally don't think that Moka was born as one but the theory's still possible.
The (umbilical) cord is not directly connected to the mother's circulatory system, but instead joins the placenta, which transfers materials to and from the mother's blood without allowing direct mixing.
However, a baby takes on the DNA of both parents. It could be possible that once Akasha became a Shinso, her DNA was altered to reflect that. DNA determines your blood-type, so I would guess that in order for Akasha to continue being a Shinso is for her body to continue to produce Shinso blood after it was introduced into her system. Once she became pregnant with Moka, Akasha's DNA would transfer to Moka.
Still, this is a LONG stretch since the manga made it clear that you CAN'T become a Shinso through heredity. I don't know why people are trying to make that connection though.
