autopolyploid A polyploid organism that originates by the multiplication of a single genome (set of chromosomes) such that all the chromosomes come from sets within one single species. Autopolyploidy has been used commercially in breeding crop plants, including sugar beet and tomatoes, to improve their vigour and growth, although the fertility of autopolyploids tends to be reduced.

autopolyploid A polyploid organism in which the multiple sets of chromosomes are all derived from the same species. For example, doubling of the chromosome number during mitotic cell division, possibly induced by colchicine, gives rise to a tetraploid known as an autotetraploid. Compare allopolyploid.
