Most ppl know this is a troll. Don't waste your time

Sarada is simply judging things by appearance and I definitely believe that there is a reason that Sarada has Karin's DNA, but Sakura is the one that gave birth to Sarada
Most people don't "know", they just assume, including you.
One correction, a mother pass half her DNA to her child. The machine that Suigetsu used looks like it showed a 100% match, so it's not that Sarada has Karin's DNA, rather that tiny black strand" that Suigetsu used was a part of Sarada herself.
The strand is the umbilical cord. Heard that it's a tradition or something for Japanese to keep their child's umbilical cord.
Nothing in the manga shows that Sarada has Karin's DNA, rather, what it shows that Karin has an umbilical cord that matches in DNA with Sarada.
The question now is why does Karin keep Sarada's umbilical cord, if she isn't the mother? Can you answer this?
