1) There's a difference between something being genetic and therefore inheritable and something producing traits that are inheritable. Being a jinchuuriki changes your body, sure. It produces traits, such as whiskers, that can be passed down to your offspring, I can buy that. But there's no canon evidence that a single sperm cell somehow carries enough of bijuu chakra to make a jinchuuriki's child a pseudo-jinchuuriki, or that sealing a bijuu inside someone rewrites the DNA of every cell in their body so that their gametes carry the bijuu's genetic information to produce its chakra in the infant.

2) You should probably note that Hashirama's cells only gave Ashura's chakra to Indra's transmigrant. Obito got nothing. Though there's no consensus on what power is Ashura's and what is Hashirama's (personally I think Wood Release is purely Hashirama) so to make it clearer - do you honestly believe that someone who infused Madara's cells would get Indra's chakra and unlock the Sharingan? Yes, Indra's power is in his eyes, and right in canon several people use his eyes (Nagato, Obito) and they're decidedly inferior, neither do they have Indra's chakra (for more proof, Obito had both Hashirama's cells and Madara's eye for several chapters and I don't think you'd argue that he'd recreated Hagoromo's chakra, because he certainly didn't show any signs of it).

3) No, someone with an implant literally has more genetic material from the source than a child. 100% match, phenotypical expression completely identical to the original, because it is the original. On the other hand, a child would get half its mother's and half its father's genes, and potentially even less phenotypical expression due to the clashing dominant/recessive alleles.

4) Beyond that, using the bijuu as a baseline it's pretty much proven that you need the physical bijuu to actually possess its chakra. Sora was filler bullshit. The Kin-Gin brothers *ate* Kurama's chakra meat. Naruto has him sealed within him, etc. You can't regenerate bijuu chakra without a source, or jinchuuriki would simply regenerate the bijuu's chakra (since, according to this thread, it somehow enters their genes) instead of, you know, dying. When Naruto literally gave the pure chakra to the Alliance, they couldn't maintain it on their own. So even if his sperm carried transmigrant chakra to his kids, how would they maintain it on their own?

The long and short of it is, expecting transmigrant chakra to be passed down to a child assumes that transmigrant chakra is inherent to a transmigrant's genes, and there's no proof of that. Chakra is quite a transcendent thing in the Naruto universe. Another case in point is Edo Tensei, where a soul is pulled from the Pure Land and completely overrides the genes, etc. of the body it is bound to, even though that body does remain and can be recovered unchanged (except dead) after the jutsu is dispelled. I expect transmigration to work much the same (they both involve reincarnation, after all). Also, there is Nagato's control of the Six Paths of Pain, which were corpses of real people. Obviously Yahiko's body and genes aren't Nagato's, even though the chakra passing through them is Nagato's.
