Why don’t bananas have seeds ?
Have you ever imagined eating a banana with seeds ? You think that it does not exist, and yet this fruit we like to taste do indeed have small seeds. But they are very well hidden … Can you guess where ?
A banana does not come as one might think of a tree, but of a herb that reproduces by rejection of roots, a bit like bamboo. If at first glance one would think that bananas do not have seeds like tomatoes or apples. In reality, this is not quite true.
This fruit has many seeds which are the small black dots that you can observe when slicing it. These seeds are in a way vegetal ovules, or seed embryos that have the advantage of not needing to be fertilized. That’s because the domestic banana, resulting from the human selection, can indeed self-reproduce itself.
The secret of banana lies in its genome: it doesn’t have two, but three copies, or 33 chromosomes in total (3 copies of 11 chromosomes). Thanks to this, the banana tree is able to reproduce without having to fertilize its fruits unlike the wild banana, which for its part, gives bananas stuffed with seeds, rather hard to chew.
Scientists have estimated that the domestication of bananas occured more than 10,000 years ago,. The banana that produces the fruits we usually eat does not exist in the wild. It comes from a cross of species, such as clementine, which is a seedless fruit from the cross between mandarin and sweet orange.
