How come some clovers have 3 leaves and some have 4?

Question

I even found one with 5.

Answer 1

It's just the different species and location.

Answer 2

Apparently, clovers with up to 13 leaves have been found. It's a misshapen leaf when it occurs, that's why they are rarer than 3 leaves, which is the norm.

Answer 3

Its like a birth deffect in humans. It's rare but it happens.
