The Daizenshuu guide series clarifies that a tail will grow ago if the Saiyan is in instant danger, as we saw v Goku in Dragon Ball.

Therefore, if a Saiyan reaches super Saiyan without being in an excellent Ape form, the tail won"t grow ago once being reduced off. If they with Super Saiyan while in good Ape form, the tail has actually an eight percent opportunity to flourish back. Since the latter info came native a video game exit this year, the isn"t clean whether this info is taken into consideration canon or not.

If you have actually brown eyes and your spouse has actually blue eyes, then you have 4 children, there is a 25 percent possibility that among those youngsters will have blue eyes due to the fact that they are recessive. Because there are four Saiyan-human hybrid children, it would certainly make feeling that at the very least one of them would have a tail if the gene came to be recessive. Gohan, the oldest, simply so wake up to it is in the one to inherit it.
