The difference between edible and inedible bananas is in seeds. Edible bananas produce fruit without any seeds, whereas inedible bananas produce a fruit with pea-sized seeds, which means that eating a banana with loads of seeds is almost physically impossible, so not all bananas are edible. All modern edible bananas are hybrids of two different mutations, Musa acuminata, and Musa balbisiana. This created a hybrid without seeds but with a lot of pulp. Hybrids derived from Musa acuminata are more likely to be used as dessert bananas, while those derived from Musa balbisiana and hybrids of the two are usually plantains or cooking bananas.
