Question

Most strains of cultivated bananas were created by crossing plants within and between two diploid species: musa acuminata (genome = aa) and musa balbisiana (genome = bb). the cavendish banana (genome = aaa), the variety most often sold in grocery stores, has what type of genome?

Answer 1

Autotriploid

Autotriploids contain three sets of chromosomes with the same type of genome/ karyotype. Each chromosome is in a triploid. The triploid results from multiplication of a haploid. It occurs in groups of three homologues. The chromosome therefore, is trisomic.
