Watching this unfold I'm constantly reminding myself of how Kishimoto has used the infusion of other people's chakras change another time after time.. Main and almost too obvious is Naruto having whiskers on his face from birth because of 9-tail Kyubi Chakra inside his mother from birth. It is very much like Kishimoto to use this trait with Sarada instead of oversimplify by outright stating that Karin is Sarada's biological mom. So I have a couple of purely speculated hypothesis about this whole situation that some people have already touched on. As far as the manga and anime... I guess we will have to wait and see. Let me know your thoughts after reading all of these.

Hypothesis 1 (using natural medical reasoning): Sakura cannot naturally conceive a child. So a fertile egg from Karin was provided since she has "insane" healing ability naturally from birth her eggs would be very well suited for this. So Sasuke and Sakura had inseminated Sarada through this science and Sakura gave birth but since the egg was from Karin, Sarada had inherited some gene traits from Karin's bloodline. Having said that; her healing prowess, visual prowess, and possible super strength from Sakura would ALL come into play when she starts to mature as a shinobi. Since in this hypothesis Sakura carried Sarada in her womb she would also have Sakura's DNA. It is explained that Karin did help in delivery of Sarada and she gave her glasses to Sarada out of fondness to her.

Hypothesis 2 (chakra explanation): We all hopefully watched and enjoyed the great ninja war, five kage summit and all the inbetweens revolving around team taka. The many many times that Karin had been bitten and infused her chakra into Sasuke. After many tremendous battles (Itachi, Deidara, Five Kage Summit, Eight Tails, Danzo)... Sasuke would grab Karin and heal himself. This amount of chakra and slight blood loss from Karin could be enough infusion of Chakra to read positive on the test Suigetsu did. Now this infusion and many uses of chakra explained by Kishimoto makes me speculate that he is going to make some very radical moves. Since Hashirama cells were imbedded into Sasuke to regrow an arm. This hypothesis would be expanded further to say that Sarada Uchiha has chakras from Uchiha Sasuke, Karin, Haruno Sakura, and Hashirama Senju.

Hypothesis 3: A combination of the above two. Having both strong DNA /gene traits of Karin and Sasuke those genes won out over Sakura's as for physical appearance. So far only dojutsu has been seen present in Sarada. Sarada is very intelligent which could be gotten from Karin who was a quick whip of smarts. But Sasuke and Sakura also were very good students themselves and Sasuke beating out most everyone besides Shikamaru.

Statement: It is stated Karins bio page that she helped deliver Sarada... so Karin is not the person who naturally gave birth to her.. also Karin gave Sarada glasses... as to the full purpose so far it seems to make her look cuter as her eyes seem to be much more fierce than Sasukes, and I would say that is because out of all the Uchiha in history (known sharingan awakening) that Sarada is the only one to awaken the Sharingan out of strong feelings of love.
