how rare is a 'three face apricot'?

Answer 1

it is just awful

Answer 2

I imagine it must be pretty rare, like a four-leaf clover. But such mutations (loss of normal symmetry) apparently do happen in plants. In animals, I think there is some mechanism at work preventing loss of symmetry. Even with lobsters, a very rare one will sometimes be found that is blue one one side and green on the other. But as far as I know, nobody yet had observed an animal with trilateral symmetry.

Even the (extremely) rare cases of infants being born with three arms or three legs are cases of conjoined twins, where on embryo starts to absorb the other in the womb, and not a case where a single embryo grows an extra arm or leg.

You might want to donate your apricot to a molecular biologist who might be able to clone it and isolate the gene defect that causes it. Future generations may have you to thank for giving them a hand!

Answer 3

Same as two-face person.
