Haploid?

Bananas are triploid. Some frogs s(a)pontaneously self-tetraploidize their offspring which cannot breed with the diploids.

Sesquiploidy would be interesting.

(The above is mostly for the sound, not the sense.)

Bananas are triploid.

Time flies when you’re havin’ fun – and fruit flies like bananas.

[Nebullis]

Multiploidy is very common. Especially in plants.
