Seedless fruit

Since eating seedless fruits is generally easier and more convenient, they are considered commercially valuable.

[1][2][3][4] Common varieties of seedless fruits include watermelons, tomatoes,[4] and grapes (such as Termarina rossa).

This is because one of the three copies of each chromosome cannot pair with another appropriate chromosome before separating into daughter cells, so these extra third copies end up randomly distributed between the two daughter cells from meiosis 1, resulting in the (usually) swiftly lethal aneuploidy condition.

Such plants can arise by spontaneous mutation or by hybridization between diploid and tetraploid individuals of the same or different species.

Fruit development is triggered by pollination, so these plants must be grown alongside a diploid strain to provide pollen.
