What is another word for amphidiploid?
Pronunciation: [ˈamfɪdˌɪplɔ͡ɪd] (IPA) 
Amphidiploid is a term used in biology to describe an organism that has two complete sets of chromosomes derived from different species. Synonyms for amphidiploid include allopolyploid, heteropolyploid, composite hybrid, and hybrid-derived polyploid. Allopolyploid denotes two different ancestral diploid species that result in the formation of a hybrid. Heteropolyploid refers to a polyploid with different chromosome sets of different ancestral species. A composite hybrid is obtained by hybridizing different diploid species, while a hybrid-derived polyploid is formed after hybridization of diploid species followed by doubling of the chromosomes. Scientifically, all these terms are used interchangeably, but they provide essential information on the origin of the amphidiploid organism.
