Musa acuminata is a wild species of banana best known for being at the origin of the vast majority of edible bananas, by itself or ithrough hybridization with Musa balbisiana. The World checklist of selected plant families recognizes eight subspecies and three varieties. Four subspecies (banksii, zebrina, malaccensis and burmannica) have been confirmed to be involved in the domestication of the banana.
Musa acuminata is diploid, that is it has two sets of chromosomes. The basic chromosome number is 11. In other words, the species' genes are distributed over 11 pairs of chromosomes.
