Other tetraploid species and conspecific diploids as sources of genetic variation for an autotetraploid.

Premise Of The Study: Most plants are polyploid and have more than two copies of the genome. The evolutionary success of polyploids is often attributed to their potential to harbor increased genetic variation, but it is poorly understood how polyploids can attain such variation. Because of their formation bottleneck, newly formed tetraploids start out with little variation.
