So, as we've seen, there are risks to taking Polyjuice Potion, and a few weird effects in general. For starters, if you accidentally take Polyjuice Potion that was made with animal fur, you turn into a furry, as shown in Chamber of Secrets when Hermione didn't join Harry and Ron in their infiltration of Slytherin's common room in order to get information about the Heir of Slytherin out of Malfoy, and they return to the bathroom after they make it out without getting caught, Hermione now has cat ears and a tail, along with other cat-like features. Another unique trait is that Polyjuice Potion isn't limited by gender, since Hermione and Bill's wife both take Polyjuice Potion with Harry's DNA in it, and when Bill's wife is changing clothing, she is shown looking like Harry in a lace bra, but with a man's chest, although she asks Bill to look away, saying she's hideous. Polyjuice Potion also carries certain defuncts, since when Hermione takes Polyjuice Potion to turn into Harry, she comments on his poor eyesight, meaning that Harry's poor eyesight carried on to the Polyjuice Potion and gave her the same poor eyesight. Back to the point, what do you think would happen if you took Polyjuice Potion with your own DNA as the sample? In other words, what would happen if Harry drank some of the Polyjuice Potion the others took before the Battle of Seven Potters? I feel like it would be similar to a divide by zero error, either that or something crazy would happen, or nothing at all.

Following that logic, could the Polyjuice have turned the others into horcruxes?

On FanFiction.Net there is a fic where if you drink your own Polyjuice after drinking someone else’s after the hour you turn back into that person with their magic instead of the drinker’s own. To Walk A Mile In someone else's Shoes by IamMegumi

It's the same conundrum in dragon Ball z, if a female fusion such as kefla got pregnant, if they defused would they still be pregnant?
