triploid
triploid Describing a nucleus, cell, or organism that has three times (3n) the haploid number (n) of chromosomes (see also polyploid). Triploid organisms are normally sterile as their lack of homologous chromosomes prevents pairing during meiosis. This can be useful to plant breeders, for example in banana cultivation: sterile triploid bananas can be propagated asexually and will not contain any seeds.
